Product Review–HP Pavillion DV7-6000 Series 17” multimedia laptop computer (DV7-6013TX)

Introduction

I am reviewing the Hewlett-Packard Pavillion DV7-6000 Series of 17” desktop-replacement multimedia laptop computers. The actual model that I am reviewing is the DV7-6013TX which is the top-end model of the series. The only differences between this and the other models in the series are the processor type, the hard-disk capacity and the optical-drive type.

One factor I am considering in this review is how these computers stand against the Dell XPS L702X, a similarly-equipped desktop replacement laptop which I recently reviewed. Both of these computers are driven by Intel second-generation “Sandy Bridge” chipsets which have integrated CPU/GPU processors.

The computer itself

Aesthetics and Build quality

The HP Pavillion DV7-6000 Series computers are finished in a black brushed-aluminium case and also have a black brushed-aluminium keyboard escutcheon. There is some of the anodised-aluminium or satin-chrome trim around the edge of the computers base and hinges, which provides for a contrasting two-tone finish.

But there is a finishing touch that hits at the Apple MacBook range very squarely. Here, the HP logo located on the bottom left of the lid reflects like a mirror when the unit is off but glows like the Apple logo on those MacBook computers when it is on. It wouldn’t be noticed as readily as the Apple logo that is positioned on the centre of the lid on those computers.

Whatever, it leads to a well-built computer that doesn’t feel flimsy in any way.

User interface

The HP Pavillion DV7-6000’s keyboard is a similarly-styled chiclet keyboard to the Dell L702x but isn’t illuminated. This is infact a common keyboard style used on most laptops nowadays. The keys are a short-throw variety which may allow for quicker touch-typing but may affect user accuracy.

There isn’t an option to determine whether pressing a key on the function-key row activates the laptop functions or a Windows-defined function like F5. Here, you would have to hold down the Fn key to select a Windows operating-system function.

The trackpad has its own area with separate primary and secondary buttons. This is even made easier with a white “neon-effect” ring surrounding the trackpad area. There are no speaker or other grilles on the palm-rest area that can be masked by your palms thus affecting the sound quality of cooling performance of this computer.

Another feature that the HP Pavillion DV7 has is a fingerprint scanner that is supported by Windows as a login measure. But this requires the computer to run HP software for the functionality to operate.

Audio and Video

The Pavillion DV7-6000 Series laptops are equipped with dual-mode graphics with Intel HD “Sandy Bridge” graphics in power-saving “economy” mode and AMD Mobile Radeon HD graphics in “performance” mode. Unlike switching a car’s transmission between “normal / economy” mode and “sport / performance” mode, these computers require all of the applications to be shut down before you change graphics modes. This will take a few seconds to occur during switchover and the unit will suggest the operating mode to use as you change between external power and inbuilt-battery power.

The screen is a 17” LED-backlit unit which works at 1600 x 900 resolution. It could benefit from having a full-HD 1080p resolution screen even if it is offered as a differentiation option. This is compared to the Dell XPS L702x which had the full HD screen as the high-end model option.

This laptop is another example of a laptop that has its audio-playback subsystem “worked” by a company who has had strong involvement in sound recording and/or reproduction. Here, the goal of this involvement is to move away from that lifeless tinny sound that typically emanated from most laptop computers and yield some decent room-filling sound that was easy to understand.

In this case, the job was done by Dr Dre’s “Beats Audio” team, who have worked the sound subsystem in the HP Envy 15 that I previously reviewed. This uses a 2.1 speaker configuration with a separate bass driver. Like the JBL improvement in the Dell XPS, this has allowed the computer to deliver room-filling sound without a that horrible “tinny” sound output common to most laptop computers. It is also worth knowing that the stereo speakers are actually placed above the keyboard so your hands don’t obstruct the sound while the computer is in use. The visual evidence of this is an aluminum grille at the top of the keyboard, between the hinges.

Some benefits I have noticed when I watched some conference videos on this computer was the clarity of the sound recorded in the video including incidental traffic sound. As well, the voices of the speakers had more of the “personal depth” in them, whereas a lot of laptops would have the voices sound like an AM radio announcer as heard on a low-end pocket radio. As well, when I played “Munich” on this computer, the soundtrack had some depth with it especially with the sound effects.

Battery life

The dual-mode graphics also allows the HP Pavillion dv7-6013TX to work for a longer time on its own batteries, especially if you are doing basic computing tasks like emailing or word-processing. Here, unlike most other laptops with discrete graphics, I had noticed that the battery wasn’t running down as fast

I had done a mixture of activities on this computer; including copy-editing and viewing of videos from a “connected-TV” conference. Yet I was able t get at least two hours of battery life out of this activity. This is although I was running the computer on the Intel graphics mode.

It was able to play through a feature-length “cinema” movie with 11% battery charge remaining at the end of the credits while on the Intel power-efficiency mode while the Wi-Fi connection was alive. This shows what the Intel Sandy Bridge chipset was all about when they promised the power efficiency for graphics-intensive tasks.

Other experience notes

The HP Pavillion DV7 doesn’t run hot as easily as a lot of the laptops that I have used. Even if the fan is run at full pelt, it makes use of the grillework on the left side and the top of the base to permit proper cooling. It may be unusual for a laptop that doesn’t have a battery “lump” or kickstand that positions it at an angle, something I have seen with a few other laptops like the Dell XPS or the HP Probook 4520 stablemate.

Limitations and Points Of Improvement

The DV7-6000 Series could benefit from a 1080 Full-HD screen especially if it is to be used for preparing or viewing Full-HD content. HP could also implement a higher-performance ATI Mobility Radeon discrete graphics chipset in the higher-end model as a key product differentiator. As well, it could support dual-band Wi-Fi networking in markets where this is permitted.

Conclusion

The HP Pavillion DV7-6000 Series laptop computers are another laptop worth considering if you are moving towards a laptop-focused “New Computing Environment” for your home or small business. Similarly, it could serve its purpose as a “work-home” laptop for business owners who primarily use it in the home or workplace and primarily travel by car. Some people may find these computers being suitable for their needs if they “live out of the car boot” and frequently drive to and stay at another person’s place for nights at a time.

This may not be as strong a performer as the Dell XPS L702X but would win on memory capacity across the series (8Gb for all models) and the mid-tier and top models having 2Tb hard disk space and Blu-Ray writing. On the other hand, this level of performance may suit most average games players or most multimedia tasks.

Windows 8–How it looks and operates is now defined

My Comments

Basic comments about Windows 8’s touch screen user-interface

A key user-interface concept in the next version of Windows will be a “Start Screen” that looks like a cross between Windows Phone 7’s home screen and the Windows Media Center interface. Here, this dashboard will have “Live Tiles” which present always-updated information in the window panes.

The applications represented on the “Live Tiles” can be a fully-fledged Windows application or a HTML5/JavaScript “mobile-like” app that links to a Web resource. This is taken further with Internet Explorer 10 implementing this functionality.

There will be the full integrated support for tablet computers and similar devices with an interface that works best with these devices as well as a regular keyboard / mouse interface. One issue that may affect software developers is that they may have to work the software so it can behave properly with a “no-keyboard” interface as well as a “keyboard” interface. Of course, the touchscreen keyboard interface will support a split layout so that the user can work the keys with their thumbs.

For some programs that primarily use mouse interaction like strategy or puzzle games, there won’t need to be much work done on having the programs work between a keyboard interface or a touch interface. But on the other hand, programs that rely on text entry such as email, the program may have to work with remapping the user interface to permit use of the virtual keyboard interfaces.

But where could this all lead to when it comes to the design of Windows-based computers?

Ever since Windows allowed for “tablet-style” computing with the Windows XP Tablet PC Edition, where the computer is operated using a stylus rather than by touch, there have been two form factors put forward to the market. One was the “slate” form factor which is like the tablet computers such as the iPad, where there isn’t a keyboard but the computer could work with a USB-connected keyboard; and the other was a “convertible” notebook computer with a screen that swivelled 180 degrees and folded flat to become a stylus-operated PC. There have been a few touchscreen variants of these form factors released subsequently once Windows Vista provided the touchscreen interface option.

The “slate” or “tablet” form factor could exist as an alternative to the iPad and Android-based tablet computers; and they could allow for operation with small keyboards for word-processing and emailing. But the computer press have forgotten about the “convertible” notebook form factor which has seen some resurgence with some manufacturers running with “netvertibles” – netbooks that have a touchscreen which can swivel between a traditional layout and a tablet layout.

Windows 8 vs the Apple platforms.

Another article had raised issues about Windows 8 becoming a competitor for a subsequent version of Apple’s iOS platform, especially the iPad implementation.

But they also raised the spectre of it competing with the next version of MacOS X, known as “Lion”. The main factor about this is that Apple were viewing the MacOS platform as a “horizontal” platform and the iOS platform as a “vertical” platform; with scant mention of any touch-enabled Macintosh computers coming on the scene.

The possibility of a granular touch-based computer marketplace

What I would see with these touch-based operating systems is the ability for hardware manufacturers to provide a granular marketplace for touch-based computing devices. This means that there could be a touch-based computing device that could suit particular users’ needs and budgets.

It would range from the 7” coat-pocket tablets serving as an alternative to a dedicated ebook reader through 10” tablets like the iPad fulfilling most general-purpose “dedicated-tablet” needs to 13”-14” convertible notebooks appealing to those of us who do plenty of emailing, word-processing or similar work on the road.

Of course, the operating environments for units that are 10” or above will differ across the marketplace in a similar way to what is happening with the smartphones. Here, users may place emphasis on factors like software availability, operating-system flexibility, battery runtime and system performance as they choose the operating environment.

Conclusion

The proposed Windows 8 environment could then become a game change when it comes to the touch-based computing environment.

Should your portable computer be a laptop or a tablet

Article

My Comments

You are thinking of a portable computer device that can stand between your smartphone and your regular 15”-17” laptop computer. But where do you go?

Tablet computers

Firstly, we have seen the tablets like the Apple iPad family and the newer crop of Android-powered tablet computers. These units have a touch-driven user interface and range between 7” for a unit that can be stuffed in to a large pocket on your coat) to a 10” unit that can sit on a coffee table. They are good for viewing previously-written material or performing limited data-entry tasks like responding to email in a brief manner, due to the nature of the touchscreen keyboard.

There has been talk of these tablet computers displacing netbooks in their computing roles but the netbooks can still work for some users when it comes to taking notes or responding to letters and they want a keyboard that they can feel properly.

Ultraportable / Subnotebook computers

On the other hand, you have ultraportable or subnotebook computers which typically range up to 14” and are optimised for portable use. These units will have a regular keyboard as well as the separate larger screen. Also, they run a regular desktop operating system in the Windows or MacOS X families, which allows them to run regular fully-functional software like Microsoft Office or work with a large range of computer hardware.

There have been some new examples of very capable 13” ultraportables that have been cited in this article. One was the Lenovo ThinkPad X1, which is Lenovo’s attempt to respond to Apple’s cool designs. This is even though it is built by a company preferred by corporate “fleet-computer” buyers due to inherent ruggedness and security features. Another is the Toshiba Portege R830 which is a lightweight Core i5-powered model with an integrated DVD drive and USB 3.0. Yet another emerges from Hewlett-Packard as the HP ProBook 5300m, a Core i5-powered subnotebook that has had its audio subsystem worked with Beats Audio technology.

The author who wrote the article for the Technology Spectator that I am commenting on even had prepared the manuscript for the article on the Lenovo X1 and had found that the proper-size keyboard had allowed him to do the job. This is in a similar experience to what I had when I reviewed the Dell Inspiron 13z last year for this site and found that this class of computer is a proper size for those of us who want a travel-friendly computer to type up work on. It is because these computers use a keyboard layout and area that is commensurate to a standard typewriter keyboard, thus allowing you to properly touch-type without your hands feeling cramped; and you also have the proper tactile feedback that you have when you operate these computers’ keyboards.

This form-factor has become very useful especially amongst those of us who do a lot of public-transport travel, especially air travel because the can easily fit on those economy-class airline tray tables; as I have seen for myself on my flight back from Sydney. Here I have seen a person who was sitting next to me have one of these machines on their airline tray-table just for viewing some video material; and they didn’t look cramped when they used that computer.

As well, they are highly valued for wireless-hotspot use because they could fit on a typical cafe table or a window / wall bench that is very common at these places. This is more so as a lot of us use the cafe as a “second office” where one can get on with their work without office-driven distraction.

The possibllity of convertible “bridge” computers

Manufacturers could consider placing in to their market “convertible” ultraportable computers that have a touchscreen so one can benefit from the bonuses of touchscreen computing as well as have something with a proper keyboard. This could be augmented with Windows 7 fully utilising its touch and tablet abilities and support for applications that have proper touch-operation benefits. Of course, there has to be improvements with battery runtime and the ability to work with multi-touch gestures.

As for “big-time” media who want to preserve their “tablet-editions” of their newspapers; they could also run desktop front-ends for the Windows platform to provide the newspaper experience to these touchscreen-enabled portable computers.

Conclusion

I would reckon that a secondary portable computer that you use should be dependent on what you intend to do with it. If you do intend to just use the device for reading and viewing material; and occasionally creating emails, I would go for a tablet computer. On the other hand, if you are doing a lot of correspondence or creating a lot of material like writing articles while out and about, a subnotebook / ultraportable could suit your needs better.

Dell XPS 15z–a Sandy Bridge laptop that snaps at the heels of the MacBook Pro

Dell XPS 15z review – Engadget

Le XPS 15z de Dell officialisé (MAJ) – Le Journal du Geek (France – French language)

My Comments

Previously, I had written an article about Windows-platform laptops approaching Apple’s “Super Cool” position on the laptop-computer equivalent of Top Gear’s “Cool Wall”.

Now Dell have come up with a 15” “thin-and-light” laptop which has a very similar look and styling to Apple’s ultra-cool MacBook Pro series of laptops. The XPS 15z, which is driven by an Intel Core i5 processor and Sandy-Bridge chipset is finished in an aluminium housing with a satin-chrome-finished magnesium alloy keyboard keyboard bezel. The keyboard has the same “chiclet” style and finish as the MacBook Pro but is illuminated and flanked by the system’s speakers in that same way.

The side of the machine is very similar to the MacBook Pro, with a slot-load optical drive and audio input/output jacks on the right-hand side and the data and display sockets on the left-hand side. You might think that this computer may end up with an illuminated Dell logo on the lid but it doesn’t.

Of course, from the Engadget review, it competes in price and power to the Apple unit but it still needs to work better on the battery runtime.

Here, it is starting to show that the aluminium or “satin-silver” metal finishes and silver-finish plastics could become a part of laptop styling, especially with “thin-and-light” designs. This is more so as manufacturers try to imitate the looks of the Apple MacBook family and see their laptops appear in the “Super Cool” section of computing’s “Cool Wall”.

Of course, it will be interesting to see whether other industrial-design cues will be implemented in designing that “ultra-cool” laptop computer that is to be noticed in the Wi-Fi-equipped coffee lounge. On the other hand, I hope that this class of computer still is useable, performs powerfully and can work for longer periods on the battery while maintaining the looks and making use of industry-standard connections.

Product Review–Dell XPS L702X multimedia laptop computer

Introduction

I am reviewing the Dell XPS L702X 17” multimedia laptop computer which is the first laptop that I have reviewed on this site that is powered by the Intel second-generation “Sandy Bridge” chipset. I have previously talked about the configuration as being something that will change the game for most desktop and laptop computers.

The computer itself

Aesthetics and Build quality

A feature that may position the Dell XPS as an alternative to the one with the glowing Apple logo is the use of aluminium finishing. This is more so with the top of the lid and the bezel around the keyboard area. As well. it is a well-built computer with a sense of quality in the manufacture of the unit.

Dell XPS L702x multimedia laptop side vent grille

Side vent grille helps keep the laptop computer running cool

This machine doesn’t get too hot too easily through normal use. It has been brought about through a battery that has a flange that places the computer on a slight angle, a large vent on the left side as well as some venting at the bottom of the unit.

User interface

The Dell XPS uses a large illuminated chiclet keyboard with a regular numeric keypad;. This is very different to other Dell laptops which I have used where there is a keyboard style not dissimilar to the typical desktop keyboard. It is still accurate for most touch-typing tasks. The only limitation that I have against it is the small top row which has the function keys as well as the ESC and “Insert”, “PrtSc” and “Delete” keys.

Dell have still marked out the trackpad as a distinct area; with the buttons kept as separate buttons rather than as zones on the trackpad. This still keeps this laptop a very useable computer without having to adopt a new learning curve.

They have also kept the function keys as their regular intended functions but you can use the Mobility Control Panel to change that option. Above the keyboard, in the indicator area, there are three touch buttons which give you one-touch access to the sound-card settings, the Mobility Control Panel as well as a user-defined option.

Audio and Video

The audio experience for the Dell XPS L702x is markedly different from the typical laptop computer that I have used. Here, I have noticed that this unit can reproduce music with a deeper bass and richer tone at a level comparable to a good portable radio;  and the dialogue and sound effects in a movie have the “full body” in them even through these speakers. This is a prime example of computer builders having compainies with audio-reproduction and speaker-design knowhow “working” their premium and multimedia laptop-computer designs to break away from the mould of “tinny” sound on this class of computer.

This example has been “worked” by JBL, one of a few companies known for extensive speaker design; as well as the use of MaxxAudio DSP logic for processing the sound. There is the option to have Creative Labs technology in the computer alongside the MaxxAudio technology and is available in this review model.

An improvement could be to move the speakers above the keyboard or on the screen so that the sound doesn’t get muffled by you resting your hands over the palm-rest speaker grilles. Of course I would find that headphones or good-quality external speakers would make this sound better.

The display subsystem is based on an NVIDIA chipset but has 3D playout functionality when connected to a suitable external display like most of the “lounge-room” TVs currently offered by most of the major manufacturers like LG, Samsung and Sony. It doesn’t seem to provide support for dual-mode “overdrive switch” in the review sample; but there are cheaper or better options that have this function but under automatic control using the Optimus feature in the new NVIDIA chipsets.

The video display handled the “Top Gear” online videos as best as the site could allow as well as some YouTube videos that I had played through the system. It as also able to hanbdle the special effects in “Munich” off the DVD very well, especially with a lot os smoothness.

Battery life

I had run this machine through a few mixed-task sessions where I had done some text editing, music playback and video playback with the machine always online through the Wi-Fi network. This was done using the default “Dell” power plan and the battery was able to cope for around two hours.

It was able to run through a DVD movie for 2 hours 33 minutes on regular power mode with the Wi-Fi network still running. This is on the standard battery that came with the system and is a benchmark that I have observed for Sandy-Bridge based laptops.

Conclusion

I would recommend the Dell XPS L702X as a desktop-replacement laptop for someone who wants to head towards the “new computing environment” but want to use a laptop that has the abilities of most current-issue standard desktop computers.

It would work well also as a work-home laptop computer for small-business owner. This is more so if you place value on the multimedia applications such as photo, audio and video editing where you need to use the latest multimedia techniques like Blu-Ray or 3D. In some ways, It could be another of those laptops that could be considered as an alternative to the Apple MacBook Pro laptop.

Simplifying login and authentication processes for WiFi hotspots

Articles

Wi-Fi body wants hotspots to override 3G • reghardware

From the horse’s mouth

Wi-Fi CERTIFIED™ Hotspot Program to Ease Subscriber Connectivity in Service Provider Wi-Fi® Hotspots  – Press Release

Wi-Fi Alliance Webpage

My comments

One main thrust behind the Wi-Fi Alliance’s new initiative concerning authentication, authorisation and accounting on public hotspots was to permit a wireless-broadband carrier to use Wi-Fi hotspots as a complimentary cellular technology. This is to avoid the need to buy cellular-telephony spectrum in order to increase service capacity and is increasingly necessary as the available radio spectrum becomes increasingly scarce.

Here, a cellular carrier could run their own Wi-Fi hotspot networks like what Telstra is doing or they could form a partnership with a wireless Internet service provider like “The Cloud” in the UK as a way of providing this service. They could then allow for a customer to seamlessly hand over from a 3G network to a Wi-Fi network that supports these credentials.

The way this is going to operate is to use a SIM card in a smartphone to store credentials for Wi-Fi networks. This card is typically controlled by the cellular carrier and may be only used for login credentials that continue the carrier’s partnerships.

A limitation I find with this is that the carrier could implement software locks so that the customer can’t use public networks other than those provided for by the carrier or their partnership. As well, there are other issues that haven’t been looked at properly with this goal for improved authorisation, authentication and accounting on these networks as I list below.

Venue-controlled hotspots

It can also make life difficult for customers who use hotspots provided by venue owners like hotels or cafes. Here, the login experience is typically managed by the hotspot owner and this may require information like a session ID in the case of a hotspot at a bar or cafe, or a room number for a hotel. These may apply for hotspot service where you pay the premises owner for that service or the service is part of the business’s main operation. In some free hotspots, you may have to click on a form to assent to terms and conditions of the service before you continue using the service.

As well, a user could use a hotspot run by an independent wireless hotspot operator and buy their access themselves through a Web-based user interface before using the service.

What I would like to see is support for these kind of hotspots because the user interface that is provided by most of them can become awkward for people who use handheld devices. This is typically because most of these user interfaces are designed for devices like laptops rather than handheld devices.

The improved interfaces could support “app-style” login experiences including “remember-me” login experiences where applicable. Other improvements that could be facilitated include the use of barcodes that are scanned by the phone’s camera to load “session keys” for docket-controlled hotspots or MMS direct-load support for login tokens for “SMS login token” WISPS. It could then lead to a venue-branded experience which some users may find as a “safety net” for their hotspot experience.

As well, a branded experience can be part of a “walled-garden” of sites that a person can visit free of charge or can be a sophisticated experience with such things as an online menu or the ability to order food and drink from your computing device.

Similarly, the idea of “franchising” WISP service to owners of venue-controlled hotspots hasn’t been worked out fully with this technology. Here, a person could have the rights to resell a WISP’s service under varying risk-return models and have the clients associated with that service use their hotspot in exchange for a cut of the costs paid by the clients.

Selective device-cluster creation

It is also a preferred standard to have devices in a public network isolated at lower network levels in order to prevent unwanted peer-to-peer discovery of the devices on these networks. This is typically achieved through functions like “AP isolation” or “Wireless Network isolation” and makes it appear to the devices that they are connecting directly to the Internet privately.

There are situations where a person may want to provide local connectivity between their own devices or devices owned by other users that are in their trust circle. Examples of this include LAN-based gaming over a wireless hotspot network, workgroups sharing data during a cafe meeting; one shifting data between a smartphone and a tablet computer at a coffee lounge or simply uploading pictures from a Wi-Fi-enabled camera to a 13” traveller laptop at their favourite “watering hole”.

Here, the authentication needed for this could be achieved through “same-token” login for devices with integrated Web browsers to entry of MAC addresses or WPS PIN numbers into a “cluster-creation” screen provided by the hotspot gateway. The Wi-Fi Alliance could examine the feasibility of using the new authentication methods as a way of creating selective network clusters across a device-isolated public wireless network.

Authenticating hotspots at the SSID-discovery level

The other question that has not been answered as far as I am concerned is whether there will be a system for authenticating hotspots and public networks in a similar manner to what is done when a user logs on to a banking site for example. This is to verify that the user has discovered a “safe” network before they select that SSID and begin to login to the hotspot.

The data that would be verified would be the MAC addresses of the access points as well as the gateway device’s  IP address and MAC address. This can be used to verify that the user has logged in to a network that is operated by the venue that is providing the hotspot service. For a WISP like “The Cloud” or FON, this may be useful for verifying that users have logged in to the WISP’s network. In this case, this information may pertain to the locally-installed hardware for the WISP.

Here, this could be achieved through a private-key / public-key exchange setup where the successfully verified hotspots could at least be highlighted in a wireless network with a ?key” or green-light icon. If this system does also support the transmission of logo icons, the client device could also show a company logo for that hotspot host.

It can also work as a way of encouraging customers to be sure of where they are surfing the Web through. As well, a business could have a Windows 7 laptop or Blackberry smartphone that supports this kind of verification for public wireless networks to prohibit logging in to public wireless networks that don’t have this kind of verification.

The main issue with this is that independently-run cafes and bars may need to be able to have access to any certification setups at a modest price, preferably through a government business-support agency or their bank.

Conclusion

Once these issues are ironed out concerning the provision of public Wi-Fi Internet service to the hordes of users with notebooks, netbooks, smartphones and tablet computers, then they can use these services to full capability in a secure manner.

Toshiba’s latest “portable-typewriter” laptop to beat according to CNET

Toshiba Portege R835-P56X Review – Laptops – CNET Reviews

My Comments

There is now a “race for the best” going on with the 13” “traveller / hotspot-user friendly” class of laptop at the moment thanks to the new Sandy Bridge technology. This is even though the netbook is appealing as a The gauntlet had been laid down by Apple with their latest MacBook Pro laptop for the MacOS X platform and everyone is trying to match this goal in an affordable way.

Examples of the improvements we will see with these computers will be improved video performance as well as an increase in the runtime available for the computer on its own battery. Some of these machines could allow for a hot-footed workday without the need to look for power outlets so you can charge up that laptop.

An example of this is Toshiba’s Portege R835-P56X laptop which uses this technology. The CNET review posted improvements in battery life by 3 hours over the previous model as well as video performance. This battery runtime period that was quoted for the Toshiba when running a video clip was nearly 8 hours, which would cover a typical workday of hotspot-surfing or public-transport working. It also is ready for USB 3.0 and can work with Wi-Fi N wireless networks.

Yet this machine still comes with an integrated DVD burner as well as 4Gb RAM and 640Gb on the hard disk. This capacity may be important when you take those digital pictures and you want to “dump” them to the computer for editing and uploading while on the go. But users may have to check their configuration comes with integrated Bluetooth when they “spec” the unit they want if they do want this function. This would be more important if you do want to pass audio to an amplifier using a Bluetooth A2DP audio module, use your favourite Bluetooth headset to Skype with or use this technology to “tether” your mobile phone to the computer.

At least the new Sandy Bridge technology could allow for this class of laptop computer to improve and become more appealing to those of us who create content while “on the go”.

The new CPU/GPU processor platforms–what change would there be for computing?

My comments about the new trend

Cost-effective system design

Due to the integration of the CPU and the graphics processor in the one chip, we will find that most computer systems will become cheaper to purchase. This will also mean that graphics performance for most multimedia and games activity will start to come at a cheaper price and be available in product classes that wouldn’t otherwise have it like mainstream-priced computers and the subnotebook / ultraportable class of portable computer.

Dual-mode graphics

There will also be an increased use of dual-mode graphics technology as a product differentiator for midrange and high-end machines. This is where a computer is equipped with integrated graphics as well as a discrete graphics chipset and the computer uses integrated graphics for most tasks but uses the discrete graphics for video editing and intense gameplay.

This could be seen like the computer-graphics equivalent of the “overdrive” or “sports mode” switch used on some cars as a way of allowing the car to work in a performance-enhanced way. Here, the user benefits from reduced energy needs and reduced battery consumption when they use the integrated graphics but can use the discrete graphics chipset when they need the extra graphics performance.

Could this change the positioning and pricing of computers?

This may have some some effect on the prices for most of the mainstream computer ranges especially if the equipment in question is to be sold with “single-mode” graphics. Of course, the “dual-mode” graphics will still be pitched at the market who place heavy importance on graphics performance like line-of-profession imaging (CAD/ CAM, graphic arts, medical imaging, etc) and “LAN-party” hardcore gamers and will still command the price premium. Here, the manufacturers can still work on performance-optimised discrete GPUs for this market and offer them in the “dual-mode” computers.

Some people may also reckon that the ability for computers based on these chipsets to perform to mainstream expectations for multimedia and gaming may allow people who value these functions to spend less on the equipment that they want. They can also place importance on “size and style” without sacrificing graphics performance.

It can therefore lead to ultra-compact computer types like 12”-14” subnotebook / ultraportable computers and small-form-factor desktop computers being offered with decent rather than second-rate graphics performance. This could, for example, make the subnotebook more appealing as a “travel workstation” for a photo journalist or other professional photographer to use when editing or previewing photographs and video footage in the field.

How to factor this in when buying a computer through this year

What I would reckon that you should do is determine what class of computer that suits your needs, including your minimum specifications for functionality. This includes hard disk capacity, RAM memory capacity, screen size, user interface, operating-system and other factors. Then look for the good deals where you can save money on the prospective computer purchase.

It may also affect the pricing and positioning of computers based on existing “separate-GPU” graphics technology especially as manufacturers move towards the new combined CPU/GPU technologies. Here, they will be wanting to clear the warehouses of these machines and you may find that the deals are favourable to you with these computers. As I said before, work out your system needs and shop around for the cheapest and best one that will suit these needs. Also take advantage of “deal-makers” that will be offered like applications software, higher-tier operating systems (Windows 7 Professional at Windows 7 Home Premium price), and extra RAM and hard-disk capacity.

Conclusion

Once the new CPU/GPU chipsets become the mainstream for desktop and portable computers, this could bring about a subtle but real change affecting the design, product-positioning and pricing of these devices.

CEBit 2011

The CEBit trade fairs are becoming a bit of a quandery when it comes to being a European launch platform for IT products targeted at the home and small-business user.This is because most of these products appeal as a crossover product between something destined for the householder and something destined for a business owner or manager.

It also cements the fact that products destined for household use like most wireless routers, smartphones and consumer laptop computers will typically end up being used in the shop or small office even though these places will use equipment targeted at business use.

Here, some of these IT product ranges could be launched in Europe at this show whereas others could be launched at the Internationaler Funkaustellung in August.

Main trends

Tablet computers

The core trends that I have observed concerning CEBit 2011 have been the tablet computers. This fair has become another launch platform for manufacturers to promote their new tablet computers which are primarily based on the Android operating platform.

Key improvements for this class have been the use of dual-core processor technology which yields faster performance.

For this class of device, this show has come at the same time Steve Jobs was premiering the Apple iPad 2 and it shows how competitive the market for tablet computers will be.

CPU/GPU combo processors

The general-purpose computing market has been thrown in to a state of flux with Intel and AMD launching processor platforms based around CPU/GPU combo processors in the form of Sandy Bridge for Intel and APU for AMD. This has changed the ballpark when it comes to integrated graphics solutions with this class of graphics solution yielding graphics performance that is above what is expected.

Similarly, NVIDIA have put forward an ARM-based CPU/GPU combination which would require a different software architecture. This has caused Microsoft to consider releasing the Windows Platform for the ARM architecture as well as for the Intel Architecture.

These processor designs have opened up a new class of computer with “superslim” notebook / laptop computers as well as more of the low-profile ultracompact desktop computers and all-in-ones. The recent work on “dual-mode” graphics where there is a discrete graphics chipset as well as integrated graphics in a computer design has become of benefit when it comes to balancing power economy and performance by allowing the discrete graphics to be seen as an “overdrive”.

Network Devices

The main trends here concern LTE wireless broadband as a WAN option for routers as well as speed increases for the popular no-new-wires network technologies. The 802.11n Wi-Fi network had been brought to 450Mbps in the form of a three-stream variant known as N450. The HomePlug powerline network had been brought up to 500Mbps but this is not yet a defined standard until HomePlug AV2 is “set in stone”. Still, this show has become a European premiere for these networking technologies.

It is more so as more European countries have deployed or are deploying next-generation broadband service to homes and businesses across the continent. What with VDSL2 projects occurring in the Germanic countries (Germany and Austria) and parts of the UK as well as various FTTH fibre-optic projects in the UK and France.

Computing Devices

Tablets

Google have released the 3.0 “Honeycomb” version of the Android operating system but have pitched it at the tablet computers rather than at smartphones and tablets. This has come at a time when more manufacturers were releasing tablet computers to the general market.

There are two main screen sizes being released – a 7” size that can be put in a coat pocket as well as a 10” size that is similar to the iPad and most netbook computers.

ASUS had launched their eeePad range of tablets with three notable devices. One is the eeePad Memo which is a 7” screen unit that is driven by a SnapDragon processor and can be operated with a stylus rather than the finger. Another unit of note has been the eeePad Slider which looks like a smartphone and has the expected functionality but can run on its batteries for 8 hours at a time. As well, ASUS premiered the eeePad Transformer which has a detachable keyboard for those who prefer to type.

There have been a few “budget” tablets that are driven by Android 2.1 rather than 3.0 and are pitched as entry-level e-reader tablets. One 8” model was pitched by AOC and had no integrated wireless-broadband modem and had 4Gb of onboard memory; while there was another 7” unit pitched by Archos in the form of the 70b E-Reader.

Of course, a few “iPad slayers” had been launched at this show. These units which are close to 10” for screen size have features, options and performance statistics that could offer more value than an equivalent iPad.

Fujitsu had released a “Slate” tablet with two cameras and could work with an optional desk docking station so that one could use standard computer peripherals like a keyboard or printer. They also fielded a Windows 7-powered “business-class” tablet PC for the corporate end of the equation.

Now, no tablet computer launch would be without the “Second Japan” (South Korea) putting their weight in with their high-value equipment. LG had launched the G-Slate which is an 8.9” Android 3.0 tablet powered by a dual-core processor, NVIDIA Tegra 2 graphics. This unit has 32Gb on-board, as well 2 cameras that are capable of 5 Megapixels each. Samsung has used this show to launch the Galaxy Tab 10.1. This is a 10” Android 3.0 tablet that uses a dual core CPU and NVIDIA Tegra 2 graphics.

Smartphones

This has also become the time when Google had set the Android 2.3 “Gingerbread” version in stone. As well, there had been talk of Nokia wanting to shift from Symbian to Windows Phone 7 for their smartphone platform.

Dell had put their foot in the market with the Venue Pro which is a Nokia-style smartphone with a slide-down keyboard.

Nokia have premiered two keyboard-enabled touchscreen smartphones in the form of the Nokia N7 and N9, with the latter one being at least Meego driven. They are also wanting to move towards Windows Phone 7 and away from Symbian as the smartphone operating system of choice for their smartphones.

Samsung have taken the chance to premiere the Galaxy S2, which is the successor to their highly-popular Galaxy S. This smartphone is equipped with a Super AMOLED display and runs Android 2.3.

Desktop and Laptop Computers

The Windows-7 computers become more powerful in their beauty and function. As well, the new combined processors in the form of the Intel Sandy Bridge and the AMD APU systems have opened up new paths when it come to designing desktop and laptop computers. Here, portable computers have been able to perform better than expected for most graphics tasks and are able to do this without a penalty on battery runtime. As well, manufacturers have been able to consider designing desktop computers that are small neat and elegant units yet able to perform remarkably well.

ASUS have released three notebooks that are of note here. One is the eeeSlate EP121 convertible notebook which has a touchscreen and a supplied Bluetooth keyboard. The screen size is 12” and it is powered by an Intel Core i5 processor. Its secondary storage comes in the form of a 64Gb solid-state drive.

They have also released the VX7 15” laptop which may impress regular “Top Gear” viewers. It has sports-car styling and uses dual-mode graphics in the form of NVIDIA GEForce GTX460M for discrete-mode and Intel Sandy Bridge Core i7 processor for integrated mode. As well, they have released a notebook computer which is 19mm thick. Here, I don’t have information about its full specifications.

Dell have run with a convertible laptop in the form of the Inspiron Duo. Here, this machine’s screen swings in a frame to “filp” from a regular laptop to a tablet computer.

Acer have premiered the iconia which is a dual-display laptop which uses two touchscreens with one as a keyboard. They have also shown the Revo multimedia desktop PC which I would describe as very similar to the slim version of the popular Sony PlayStation 2 games console. As well, Shuttle, a manufacturer of small-form-factor PCs have released a computer that is based H67 “Sandy Bridge” chipset.

Peripherals

The computer display scene has been centred around large-screen HD monitors. One of these is in the form of the ASUS P246Q 24” LCD screen for graphics artists. This one could work in landscape or portrait mode, has an A4 aspect ratio, and a resolution of 1920×1080. For connectivity, this 499-Euro display has the DisplayPort, HDMI, DVI and “VGA” connectors as well as an integrated USB hub.

BenQ have offered a 24” Full-HD LED-backlit LCD display This 300-Euro display has for connectivity 2 HDMI sockets, and a 4 USB hub as well as the usual DVI and VGA connectors but could offer a DisplayPort connector. They also released an “interactive projector” that needs no stylus and allows the user to touch the projected image to interact with it.

Creative have released a few HD-resolution webcams in the form of the Socialize HD which is equipped with auto-focus and available as a “full-HD” (1080) model and an “HD” (720p) model/ They have also released the “Cam Chat HD” which doesn’t have auto-focus but works at HD (720p).

Every technology trade show will come up with the usual line of peripherals and gadgets that may not appeal to the serious computer buyer but appeal to the computing press as sidelines. One is that Fujitsu had released a regular computer mouse that was to “appeal” to the green thought by having it made out of renewable materials. In my opinion, this wasn’t anything special as far as pointing devices go.

SAGEM had released a cordless phone which reminded me of one that was released in the late 1970s by a mail-order firm in America. Here, the battery-powered cordless phone was designed like a standard corded desk telephone yet it transmitted via radio to a “black-box” base station that was connected to the telephone service. It was initially modelled on the standard-issue dial telephone of the day but was revised to look like the standard-issue pushbutton phone of that same era. The cordless phone offered by SAGEM and known as the “Grundig Sixty” was styled like a dial-equipped desk telephone that was standard-issue in Germany in the late 1960s except that this DECT-connected phone uses pushbutton dialling and is finished in that orange colour reminiscent of the era.

The network

For the network, this has become a European launch pad for N450 (three-stream 802.11n that runs at 450Mbps maximum) Wi-Fi equipment as well as 500Mbps HomePlug AV equipment.

AVM, the German network-hardware name have become an example of this with their FritzBox routers have been conservative with their N-based WiFi speeds by offering N300 for their Wi-Fi networks rather than running for the N450 three-stream technology. One of these is the FritzBox 6840 which has LTE wireless-broadband on the WAN side and one Ethernet as well as Wi-Fi N-300 on the LAN side. Like most of the other FritzBox routers, it has VoIP telephony interfaces through 1 telephone socket and a base station for 6 DECT handsets. As well, it has a USB socket for sharing peripherals as well as being a DLNA media server.

They also premiered the Fritzbox Fon WLAN 7330 which has ADSL2 on the WAN side and Gigabit Ethernet as well as Wi-Fi N300 on the LAN side. This would have the USB port and DLNA media server function as well as a VoIP endpoint for 1 regular handset and 6 DECT handsets.

They also released a companion DECT cordless handset for these routers which looks as though it is a low-tier camera-equipped mobile phone. Here, this would use a colour LCD display and a graphic user interface for its management and use; and is pitched as an Internet audio endpoint.

Of course, they have released a HomePlug AV 500Mbps set with two HomePlug-AV – Gigabit-Ethernet bridges for the European market.

TP-Link have started to push in to the European market as far as their HomePlug products are concerned, This is with them premiering an energy-saving HomePlug AV network bridge with power connector so you don’t lose your power outlet when you plug in the HomePlug.

Conclusion

The CEBit 2011 trade fair is the first such fair for an interesting year in information technology, what with combo CPU/GPU chips, higher network speeds and increased interest in the touch-driven user interface.

Understanding the new Thunderbolt peripheral-connection technology

Another of the new technologies that Intel has been promoting alongside its “Sandy Bridge” processor architecture has been the “Thunderbolt” peripheral connector.

Capabilities

This connector has a current raw transfer speed of 10Gbps but could have a theoretical maximum is 40Gbps (20Gbps up and 20Gbps down) when both pairs of wires are used. You can use this same “pipe” to pass a DisplayPort-based audio-video stream for a display as well as PCI-Express-based data stream.

There is the ability to daisy-chain 7 Thunderbolt-connected devices but you can have less than 3 metres between the devices at the moment.

Thunderbolt at the moment

This technology will complement USB and other connection technologies but will be like what happened with USB in the mid-90s. This means that it will be an Apple-only technology and this will appear on the latest run of MacBook Pro laptops.

It will appear on PC-based computers in early next year. As far as retrofit opportunities go, Intel had mentioned that it could be available for new motherboards but there was nothing much said about availability as an add-in expansion card.

The main peripheral applications would be external storage subsystems like the LaCie “Little Big Disk” storage array; as well as displays. Such peripherals that have this connection will typically be marketed as being “Thunderbolt-ready”.

What could it offer

Another storage-expansion connection for computing devices

One key application would be to provide a high-bandwidth direct connection between computer devices and one or more external hard-disk storage subsystems. The reason I use the term “computer devices” is because such devices could encompass PVRs which could benefit from capacity expansion, routers and network devices that convert attached external hard-disk subsystems to network-attached storage; as well as the general-purpose computers.

Multifunction devices that are fit for the new generation of compact high-performance computers

There is the possibility for one to exploit the Thunderbolt concept to design a multifunction desktop console unit. Here, this unit could house a screen, audio subsystem, video camera, removable storage such as an optical drive or SDXC card reader and/or a USB hub. Another variant could house a keyboard instead of a screen and connect to one or more external displays using DisplayPort or regular monitor connectors.

This display unit would be connected to an ultracompact system unit that has only the processor, RAM, graphics-processor, network connectivity and a hard disk, plus some USB sockets for a desktop application. On the other hand, this display could serve as a “desktop display” for a subnotebook or ultraportable computer. The USB hub would come in handy for connecting keyboards, mice, USB memory keys and similar devices.

Here, these multifunction devices can be designed so that they are no “second-class citizen” because they have multiple functions. This means they could render the multiple video streams as well as support the high-capacity removable storage technologies like Blu-Ray Disc or SDXC cards.

This is more so as the Intel Sandy Bridge technology makes it feasible for small computers like book-sized ultracompact desktops and notebooks of the “subnotebook” or “ultraportable” class to “have all the fruit” as far as performance goes.

Issues that may be of concern

One main issue that I would have about the Thunderbolt technology is that Intel could limit it to computer applications that are centred around its chipsets. This would make it harder for competing processor designers like AMD or NVidia to implement the technology in their chipset designs. It would also place the same implementation limits on system designers who want to use chipsets that offer improved performance or better value for money alongside Intel processors on their motherboards.

This is like the Intel Wireless Display technology which allows a special display adaptor to connect to an Intel-based laptop computer via a WiFi wireless network and show the pictures on the attached display device. Here, this functionality could only work with computers that have certain Intel chipsets and couldn’t be retroactively applied to older computers.

Another issue would be to encourage implementation in “embedded” and dedicated-purpuse devices like PVRs and routers as well as the general-purpose computers. For some applications like the previously-mentioned storage-expansion application, this could add value and longer service life to these devices.

Conclusion

Once the Thunderbolt technology is implemented in a competitive manner, it could open up a new class of devices and applications for the computing world by making proper use of the “big fat pipe” that it offers.
