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.

Product Review–Western Digital WDTV Live network media adaptor

Introduction

I am reviewing the Western Digital WDTV Live network media adaptor. This is and adaptor that connects to an external display like a TV, monitor or projector and/or an external amplifier in order to play media files held on a local storage device like a USB memory key or via a small network.

The device itself

The unit's remote control

It is a small device about the size of two packets of cigarettes stacked on top of each other and is powered using a power adaptor. Users operate it with a very small remote control that has the main transport functions and a D-pad for navigating around the user interface.

Setup

Western Digital WDTV Live network media adaptor connections

How this connects to your TV

The device connects to the TV using an AV cable that plugs in to a four-conductor 3.5mm jack on the back of the unit. There is another 3.5mm four-conductor jack for connecting to the component-video connections on a suitably-equipped display device with a separate patch cable. Of course, this unit can be connected to HDMI-equipped display devices like most plasma and LCD TVs; and it has an optical SPDIF socket for connection to equipment with an optical digital input like most surround receivers.

Sadly, this device doesn’t support connection to display devices that use RGB inputs in any form. This may affect those of us who want the best out of monitors or projectors that use such connectors like most SCART-equipped European TVs, business-focused “data projectors”, classic “3-gun” projectors or professional-grade video displays. You may get around this by connecting the device to the display via one of the “HDFury” HDMI-RGB adaptors

It has the ability to play media that is held on USB-attached storage devices like memory keys or USB hard drives. This can be useful for playing media that you have held on one of these devices.

As for video codecs and file types, it can natively handle most audio and video file types including the DivX and Matroska MKV family of file and codec types.

Network setup

The WDTV Live HD can be connected directly to an Ethernet network or HomePlug AV network with the appropriate “homeplug” bridge device, But it is one of these “wireless-ready” devices that connects to a Wi-Fi network using an optional Wi-Fi dongle available from Western Digital or through one of their retailers.

Use

Western Digital WDTV Live network media adaptor in use with older TV

This can work with any display device including older TVs

The user interface is a “full-screen” one which works to the edge of the screen. This may be of concern with those of us who have hooked the WDTV Live up to an older CRT-based TV set that has the orthodox curved screen edges. As well, the logos for the Internet services are rendered in a dull manner and could benefit from “true-colour” display with a highlight around the currently-selected service.

Of course, there is a screen-saver function which can be overridden for displays that aren’t affected by long-time display of images or set to appear after a time between 5 minutes to 15 minutes. Here, it just shows the WD logo; but could show now-playing information during audio playback.

Online services

The Facebook service has the expected functions like viewing one’s own news feed, contributing to a Status Update or writing one’s Status Update as well as the ability to view one’s Photo Albums or a Friend’s Photo Albums. All text entry is based on “pick-n-choose” methods and the pictures do come up properly on the full screen.

I have tested the YouTube service with this device and have used it to play some videos including the service’s “poster child” video which is the “Keyboard Cat” video. The user interface is what would be expected for a 10’ interface and the users would be required to use the “pick-n-choose” method for any text entry like account login or video searching.

The “Tune In” Internet-radio function works properly for Internet radio access and allows the Internet radio stream to play in the background while you navigate the menus. During the day, It had performed well on quality-of-service when streaming Internet radio; but like all Internet services, this will depend on how congested the connection is.

UPnP AV / DLNA media access

The UPnP AV / DLNA functionality on the WDTV Live works properly when you use the remote control to call up the content on your UPnP AV / DLNA Media Server. In previous firmwares, this media player had problems when playing out media under the control of a UPnP AV Control Point like Windows 7 or TwonkyManager. Here, it would play only one item at a time and require the user to advance the media to the next item using the remote control or the Control Point.

Now, units that have firmware newer than version 1.65 can play multi-item playlists and slideshows without needing to be “pushed on”. There is still a problem with this function, especially with image slideshows and video playlists where the unit will show its menu every time a new image or video is loaded up before it plays that image. This could be improved with “read-ahead” buffering for subsequent media items.

Limitations and Points Of Improvement

I would like to see the user-interface improved in various ways, such as use of brighter colours or full-colour logos for the Internet services.  The screen-saver could also support “service-driven” behaviour like showing now-playing information for audio sources.

As well, this device could benefit from integration with local online-video services like the local “catch-up TV / video-on-demand” services offered by the local TV stations. Of course, I would like to see an improvement on the media changeover behaviour when the device is used as a UPnP AV / DLNA MediaRenderer under the control of an external control point.

This device’s form factor could be taken further with an integrated digital-TV tuner for implementation as a digital-TV set-top box that could have online and network media access as well as digital-TV access.

Conclusion

I would recommend the Western Digital WDTV Live or any of its successor models as a cost-effective device that can be useful for pressing a cheap or old TV, monitor or projector in to service as a network media playback device in the UPnP AV / DLNA Home Media Network.

With two new standards in the works, we could be approaching the Gigabit wireless network

Articles

Understanding gigabit Wireless LAN: 802.11ac and 802.11ad

My comments

What is it all about

At the moment, 802.11n on both the 2.4GHz and 5GHz wavebands is the current link standard for the Wi-Fi wireless network. But the IEEE have decided to work on standards for providing increased-bandwidth wireless networks.

The two standards are 802.11ac, which will primarily work on the 2.4Ghz and 5GHz radio bands and be seen as a migration path from the current 802.11n technology; as well as 802.11ad which works on the 60GHz waveband and has a very short range. The latter technology would be considered best for peer-to-peer applications like short-range wireless backhaul.

Both of these systems will use MIMO (Multiple Input Multiple Output) radio technology; a “front-end diversity” system with multiple transceivers which is what the 802.11n network uses. But this technology will work with at least four “front-ends”; known as “4×4” due to four signals coming in and four going out.

Dedicated bandwidth options

One major benefit that I see with these technologies will provide is dedicated-bandwidth wireless networking which each access point compliant to these standards can do. This is brought on through the use of MU-MIMO (Multi-User Multi-Input Multi-Output) Here, it extends “transmit beamforming” technology which provides improved signal quality in an 802.11n network to allow the access point to provide “switched” Wi-Fi with dedicated bandwidth to stations; similar to the way the typical wired Ethernet network works.

It may be an improvement for network setups with many SSIDs per access point like so-called “guest / hotspot” + “private” networks, shared hotspot access points or many university networks; by allowing full bandwidth to each SSID.

The realities

Of course, the actual throughput that a network link will achieve will typically be less than headline link speed due to overheads associated with the link’s transmission requirements. Here, the average real world maximum throughput will be 867Mbps and the figure may be quoted for first-generation equipment or mature-generation equipment.

How it affects my small network

What will be asked of a small network like a home network would be a 5GHz segment that provides the 802.11ac network.

It may provide for dedicated throughput to client devices like laptops or tablet computers. For those networks that run as dual networks like hotspots or guest networks that share the same wireless router as the private network,the dedicated throughput for each wireless-network segment will be a bonus.

Of course, 2.4GHz will still be used as an 802.11n segment for existing devices and there may be a compatibility mode so that existing 802.11n devices can operate on the same segment.

Other issues

If the 802.11ad technology is to be used as a wireless-backhaul for many 802.11ac access points, there will have to be work on a complementary mesh-network technology. It will then provide a level of fault-tolerance in the wireless backhaul as well as a chance for each station to have and pass on full bandwidth networking. This is something that the IEEE standards body are working on with the 802.11s draft standard.

Conclusion.

It therefore shows that when there is a standard in place, there will be a chance to “raise the bar” with the technology that it covers. This will mean that a Wi-Fi wireless network could become close to the goal of a switched Gigabit network.

London to assist rural communities with access to real broadband

Article

BBC News – Devon, Norfolk, Somerset and Wiltshire get faster broadband

My Comments

There have been a few efforts to deploy broadband Internet service into rural Britain that matches or betters the similar service available in urban Britain as I have covered previously on HomeNetworking01.info. Some of these have been underpinned primarily by local private companies with, in some cases, help from local government.

Now, London has come to the fore through the establishment of Broadband Delivery UK and the national funding of rural broadband projects. Four of the first few projects that have been started on under this funding are in Devonshire, Somerset, Norfolk and Wiltshire.

The funds allocations are GBP30m for Devon and Somerset; GBP15m for Norfolk and GBP4m for Wiltshire. Of course, the local councils and private investors in all these areas will provide supporting finance to the broadband provisioning effort in their areas.

An example of this is the Devon County Council pledging GBP22m towards the effort in their area. Here, their goal is to have at least 85% of Devon’s residents having access to the superfast broadband Internet service with a rated speed of 16-20Mbps at the end of the project.

The rhetoric put forward by the UK’s Cultural Secretary is that broadband Internet service is to be a common utility for homes and business in the same vein as mains electricity and telephone. They even have a goal to have the United Kingdom to be known for super fast broadband Internet service in Europe by 2015.

There was no talk about what kind of technology was going to be used to provide the service “to the door”. It then opens questions on whether a particular area was being provided with fibre technology or wireless technology; or whether the “last mile” to the customer’s door was to be copper, fibre or wireless links.

Of course it is so easy to think about whether an area will be covered by a broadband improvement drive but it is worth making sure that the service arrives at the customer’s door at the proper standard. This includes questions about how farms and similar properties are to be covered and the issue of older telephone wiring in rural areas, a factor that is increasing real when deploying cheaper “copper-in-the-last-mile” setups like VDSL2 FTTC systems.

Product Review–Brother HL-2240D compact direct-connect monochrome laser printer

Introduction

I am reviewing the Brother HL-2240D monochrome laser printer which is the second in line in Brother’s latest series of compact monochrome laser printers. There is a cheaper version of this printer, the HL-2230, which doesn’t have the auto-duplex functionality. On the other hand, the HL-2250DN and HL-2270DW printers have the same functionality as this model but can be connected to an Ethernet network or HomePlug powerline network with the appropriate adaptors; with the latter model being able to be connected to a Wi-Fi network as well.

It is also worth noting that the HL-2270DW model, which is the Wi-Fi-enabled top-shelf model of the series had won the Buyer’s Laboratory “Pick” Award for A4 SOHO printers.

The printer itself

Like its low-end laser-printer peers, the Brother HL-2240D and its stablemates are very compact printers that is very shallow, slightly higher than two large-city telephone directories stacked on top of each other. This means that the printed documents are easy to reach from one’s chair and it doesn’t take up much bench space.

Usage experience

The software that came with the printer had installed on my computer very properly and had operated true to the Windows 7 specifications. As well, the user-interface screens for the driver are very easy to use, being able to show on the left side the settings you have implemented for your print job. This is a very similar experience that I had with the driver software that I had for the Brother HL-4150CDN colour laser printer when I reviewed that unit; and has demonstrated to me that Brother has made strong efforts with their software’s useability.

The Brother HL-2240D printer and printers based on this similar print engine take between 6 to 8 seconds to warm up and be ready to print. It doesn’t matter if this printer has been just used or not.

There is a significant time penalty with this printer for duplex printing, where the machine will take twice as long to turn out documents. This is because it can handle only one page at a time through a duplex print cycle; and will likely be a problem with compact laser printers that use this feature.

The printer uses a manual feed slot for labels, transparencies, envelopes and similar material and these materials have to be loaded one at a time. There may be some materials that have to pass through the printer in a straight-through manner similar to the old photocopier or original Apple LaserWriter printer. Here, there is a drop-down hatch on the back of the printer to cater for these requirements.

There isn’t a “fuel-gauge” for the toner, a feature I would find useful when working out the effect of a large print run on the machine’s toner supplies. The only way the user knows if the printer is out of toner is through the “TONER” light on the top of the machine flashing when it is very low and this same light glowing steadily when they need to replace the toner.

What is required to be removed to replace the toner on these printers

When you have to replace the toner cartridge on the Brother HL-2240D and its peers, you have to remove the drum unit from the machine then release the toner cartridge from the drum unit by operating a small green latch on the left side of the drum unit. This process can appear to be very fiddly compared to other laser printers that I have reviewed, where you could just simply pull out the spent toner cartridge from the printer after opening the access door / lid and, in the case of the colour lasers, pulling out a drawer. It is also prone to mistakes and reduced printout quality if the user doesn’t know where to “park” the drum unit while replacing the toner cartridge.

Print Quality

The output quality is what you would expect from a laser printer when it comes to text, with the sharp lettering that is typical of this class of printer. But give it a photograph to be printed in greyscale and you will have some banding across the page. As well, the pictures come out slightly darker even though they are printed on plain paper. This is usually due to these printers having their prowess anchored around document printing.

Limitations and Points Of Improvement

An improvement that I would like to see would be an easier-to-replace toner cartridge. This is where the drum unit can be pulled out just enough to remove and replace the toner cartridge without the need to operate any catches.

Similarly, these printers could benefit from an on-machine or driver-based toner “fuel gauge” indicator. This is so that one can know where they are at with the toner supply for their units.

Conclusion and Placement Notes

I would recommend that the Brother HL-2240D or HL-2250DN printers be considered for applications like most small medical or legal practices; small hotels or independent travel agents where there is a strong likelihood of turning out standard documents where colour doesn’t matter like invoices, health-insurance forms or itineraries.

Similarly these two printers could be used in a lawyer’s, psychologist’s or other similar professional’s office for turning out confidential information for their patients or clients. It is also augmented by the fact that these printers could easily just occupy the space of a small table like the archetypal side table; which may befit one of these professional’s offices.

The HL-2250DN would suit applications where there are two to five computers sharing the one printer or the location uses laptop computers connected to the network via Wi-Fi wireless. If this was used in a Wi-Fi-based location, this printer would be connected to the network via Ethernet or HomePlug.

DLNA now meets Pay-TV setups

Articles

New DLNA Interoperability Guidelines Will Turn Your TV Set-top Box into a Home Server | eHomeUpgrade

From the horse’s mouth

DLNA Press Release

My Comments

DLNA have released a set of interoperability guidelines for networked equipment that can play premium pay-TV content, whether live or recorded across the home network while keeping it secure. This is based on the DTCP-IP link protection protocols so as to protect the content from being re-streamed in an unauthorised manner.

AllVid and similar initiatives

These guidelines will lead to the acceleration of the “AllVid” initiative that has been put forward to the FCC by the likes of Sony and TiVo. This is a way of providing an open scenario so that people can use equipment they have bought with their pay-TV services in the US rather than having the TV just become a display for their set-top box leased from the cable company.

The idea behind tis concept is that there is a “gateway” device that connects to pay-TV broadcast services like cable, satellite or IPTV. This device connects to TVs, set-top boxes and PVRs via the home network using DLNA-specified technologies and is responsible for bridging the broadcast content to the home network as well as managing the access-control to the premium content on the pay-TV service.

If it receives broadcast content from terrestrial, cable or satellite services, it would use one or more RF tuners and circuitry to present the broadcast channels as network streams as well as authenticating and authorising the pay-TV content. On the other hand, an IPTV setup which connects to the home network would simply authenticate the content and present it across that home network.

It also will provide for situations where the user may change to a different pay-TV service that uses different technology or move to a different area that uses a different pay-TV service without losing their investment in their equipment.

OCAP-compliant “Tru2Way” cable-TV setups

The first main implementation would be cable-TV systems that are based on the OCAP-compliant “Tru2Way” platform. These will have a regular set-top box with separate security measures that can work across the different cable-TV setups. As well, they would be a DLNA server that works to these guidelines, providing the channel lineup that the customer has subscribed to as well as programmes recorded on this set-top box to the compliant TV equipment.

Of course, the main application with this could be to serve the content out to secondary TVs that are compliant to this standard or are connected to video peripherals that again are compliant. It could also lead to the main TV being connected to a “video server” set-top box

The main difference between these setups that one should know is the kind of “skin” that is expected on the user interface. The “AllVid” user interface is expected to have the viewing device’s branding like Sony’s XrossBar rather than the media-provider’s. Conversely the Tru2Way platform is meant to have support for the content provider’s or service provider’s “skin”. This also includes the creation of DVD-style menus and user interfaces along with the enablement of full interactive television apps like voting up that favourite dancer or singer on that talent-quest reality show.

Questions

Pay-Per-View services

A good question that hasn’t been answered so far is how this will enable the initial purchase of “pay-per-view” content. Most pay-TV operators run one or more pay-per-view content services, either in the form of one or more broadcasted events that is sold in this arrangement or a “movie-on-demand” or “virtual cinema” service with a few of the latest blockbuster movies shown across multiple channels.

The current problem is how can a user instantiate a pay-per-view content purchase in one of these setups using the TV’s remote control; and seeing it through so that the content is available and duly authorised. This includes allowing the account owner to place controls on what pay-per-view content can be purchased in their home.

What do customers look for in the new equipment they intend to purchase

Also, customers need to have something to look for when they purchase TV equipment so that they are sure that the equipment is compatible with DLNA’s premium-content requirements. This could include a “super-logo” that is exhibited on compliant equipment, with the equipment having to support the DTCP-IP functionality as part of this functionality set.

Retroactive upgrading of current equipment

The other factor that needs to be looked at is whether this DLNA premium-content-handling functionality can be brought to existing DLNA-compliant hardware such as the current crop of Sony and Samsung TVs through a firmware upgrade; or whether they would need to replace the existing hardware to gain this functionality.

This will be more important with TV sets as people who upgrade TVs will end up deploying their existing sets to other rooms of the house or to other locations.

Conclusion

At least the use of DLNA technology and the extension of broadcast-content-protection methods to the network could make it easier to allow flexible equipment setups in most mainstream viewing applications.

Should your portable computer be a laptop or a tablet

Article

Business laptops reload | Technology Spectator

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

Articles

Dell XPS 15z available in Australia and Asia, fits Sandy Bridge in under an inch of thickness – Engadget

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.

Introduction

I am reviewing the Canon PiXMA iP100 Mobile Inkjet Printer which is the current-generation successor to the popular Canon BJC-80 portable printer. This particular model has appealed to those of us who need to use a printer to obtain hard copy “on the road” from our portable computer devices.

I have been lent this unit for review by a close friend of mine who had bought it to go with their netbook computer that they were using for an overseas trip they had previously done. This was intended to be used for occasionally obtaining hard copy of emails and similar documents through that journey.

The printer - ready for travelling

The printer itself

The Canon PiXMA iP-100 is a very small lightweight printer that occupies the table space that a typical netbook computer would occupy. This makes for reduced storage space that this class of device would require as you travel.

Like its former grandparent model, the BJC-80, this printer is able to work from AC power using a supplied power adaptor which connects to the AC power through the typical “portable-radio” power cord; or from an optional rechargeable battery. You can also buy another power adaptor that plugs in to your car’s or boat’s cigar-lighter socket so you can run it from the vehicle’s battery. From my searches on the Internet about this battery pack, it is rated to allow the printer to turn out 292 pages on one charge.

This printer is a direct-connect printer which can connect to the host using a regular USB cable or wirelessly with IRDA infrared connection or Bluetooth radio connection. The latter method can be achieved if you purchase the optional Canon Bluetooth module and plug this module in to the PictBridge USB socket.

It does support driverless printing for devices in certain situations. The first one would be wireless printing from phones and PDAs that support Bluetooth and IRDA “object-push” profiles for small documents and photos. The second situation would be for digital cameras and mobile phones that have a PictBridge connection.

This latter function can come in handy if you need to print out “example images” or “pre-approval” proofs to show to customers after you have just taken a picture. Of course, some of us may find it useful for printing out the quick snaps to pass around after we take some funny pictures.

Computer functions

The software loaded properly on my Windows 7 computer and it didn’t take a long time for the computer to “re-discover” the printer on subsequent connections. This would suit its intended market where the printer would be brought out and connected as required.

Output Quality

The printer will turn out very sharp text that would yield a very easy-to-read document. When I print photos,there is strong contrast but sometimes there may be a bit of paleness in the picture. For colour reproduction, there is still some strong colour saturation and it can properly reproduce the skin tones.

Limitations and Points of Improvement

The Canon PiXMA iP-100  could benefit from higher-capacity cartridges, especially high-capacity black cartridges. This is especially more so if it is to be used by a tradesman like a repairman who has to turn out multi-page quotes or invoices; or if it is being used frequently to turn out “proofs”. As well, it could improve on the printer’s operational economy.

In the same context, the printer manufacturers who sell “mobile” printers could do some research in operation-economy-improving techniques like four-cartridge printing and higher-capacity cartridges.

As well, there could be some work done on making it feasible for smartphones and tablet computers to print out using the iP-100. At the moment, this may require use of the Bluetooth module as well as iOS and Android apps that link with the email, photo-viewing and document-creation functions of these devices.

Conclusion and Placement Notes

I would consider this Canon PiXMA IP-100 portable printer as being suitable for basic printing needs that occur primarily in the field like printing quotes and invoices to hand directly to the customer for example. It would also work well for business travellers who need to obtain hard copy of documents or photographs without the need to pay higher costs or face embarrassment when using other equipment.

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.

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.
