Sony Vaio Tap 20 Review – Watch CNET’s Video Review

My Comments

We have seen the desktop-replacement laptops with the 17” displays as the pinnacle of the laptop computer class but Sony has introduced a new computer device class that bridges two other computer classes. This is part of an increased run of touch-enabled computers that take advantage of the Windows 8 touch shell.

This computer, known as the VAIO Tap 20 is a bridge between the tablet computer and the all-in-one desktop computer of the ilk of the VAIO J Series that I reviewed. Here, it is a Windows 8 tablet with the multi-touch user interface, but it can rest on a stand which links to a keyboard and mouse for regular all-in-one use.

It has 4Gb RAM and 750Gb on the hard disk but doesn’t have an integrated optical drive or HDMI video input. The screen comes in at 20” with a 1600×900 resolution while it is powered by an Intel i5 third-generation processor.

The CNET article still found this computer to have what they considered as dubious performance abilities of the all-in-one class and they found that, although it runs the Windows 8 operating system and has the NFC abilities, it is not worth the money. This is although the HP Z1 Workstation and the Malmgear Alpha 24 Super are showing up as highly-capable all-in-one computers that can handle advanced graphics for work and play.

But what I see of this is that it could be a proving ground for this computer class as more of the all-in-one computers come on the market in response to Windows 8. This is in the form a a large tablet computer which can work as a desk-based computer. Once Sony or someone else issue a “follow-up” model that has the better specifications and features, this could be a chance to legitimise the “all-in-one” tablet hybrid computer as a credible computing device.

Introduction

I am reviewing the Toshiba Tecra R950 which is Toshiba’s latest iteration of their work-home business laptops. This has business features like business-grade security and a shock-proof hard disk but is based on the new Intel 3rd-generation hardware platform. It also benefits from expandability options like an ExpressCard slot and plenty of USB 3.0 sockets.

The unit I am reviewing is a mid-tier high-performance variant but this series has cheaper variants that have less RAM and the cheaper i5 processor while there are higher-performance variants with a 256Gb solid-state disk and dedicated graphics processors.

The computer itself

Aesthetics and Build Quality

The Toshiba Tecra R950 has that business look about it. It has the dark grey lid and a herringbone ribbed palmrest and is finished in the dark grey colour. Only the hinges are finished in chrome, with the right hinge being used for locking down the computer with a Kensington-compliant cable lock.

It is built well for durability, and does feels heavy. This characteristic is one where you could expect a long lifetime out of this business-class laptop.

When I was watching some on-demand video, I had noticed that the Tecra didn’t run hot. This is usually a time that I notice that a laptop can run hot with the cooling fan running at full speed and / or the computer feeling too warm. This is even though the vent is on the left side of the computer and I felt minimal hot air leaving that vent.

User Interface

The Toshiba Tecra R950 has the same roomy keyboard with the hard plastic feel which does lend itself to comfortable accurate typing. There is also the separate numeric keypad which is a boon for entering lots of numbers in to that Excel spreadsheet or accounting program.

The trackpad still works as expected and can be sensitive if you are typing but you can still override it using a hardware button located below the spacebar. At least the thumbstick works properly as an alternative pointing device so you can have the trackpad off if you find its sensitive behaviour annoying.

Audio and Video

Left-hand-side connections – VGA, DisplayPort, USB 3.0, ExpressCard 34 slot, SD card slot

I have noticed that the audio and video experience that this Toshiba Tecra R950 has given me is smooth for most tasks including audio and video playback. The video playback was still very smooth even through film scenes which may be dificult to reproduce. As for the sound, it cam through very clearly through headphones but the integrated speakers still leave room for improvement.

Connectivity, Storage and Expansion

The Toshiba Tecra R950 has many different ways to connect external peripherals to it. For example, there are many ways to connect an external hard drive to this laptop without trading performance – an eSATA / USB 2.0 connector as well as two USB 3.0 connectors.

Right-hand side connections – 3.5mm audio input-output jack USB 3.0 port, USB 2.0 port, USB 2.0 / eSATA combo port and DVD burner

There is the DisplayPort socket used as the digital video connect and you would need to use an adaptor when connecting to HDMI or DVI displays such as most flatscreen TVs. Of course, there is a VGA socket for use with legacy video equipment like the cheaper projectors.

As for secondary storage, the Tecra business laptop has 640Gb as its primary hard disk capacity although some of the more expensive variants come with a 256Gb solid-state storage option. This is supplemented with a DVD burner and a SDXC card reader, thus having access to cost-effective removable storage without the need to carry extra accessories.

The Tecra is equipped with an ExpressCard 34 slot. This gives it room to expand in functionality because you can plug in wireless-broadband modems, sound modules and the like yet have the high performance. SD card slot being located directly under this can be obstructed by ExpressCard modules that use a large overhang

Battery life

The Toshiba Tecra R950 was able to run for a long time on its own battery for most activities as I have observed. For example, I was able to run it with video-on-demand for an hour and find that there is 75% of power left in the battery. As well, I had the Tecra play a feature-length movie DVD for five hours and 21 minutes before the battery ran out after just charging the battery.

This is something I would expect of a full-size 15” business laptop running newly-issued batteries and would preserve its credentials for long flights or similar activity.

Limitations and Points Of Improvement

An option that I would like to see for the Toshiba Tecra R950 and other larger laptops that come with the high-capacity hard disks is a solid-state disk that works as a cache drive to improve performance and battery runtime. Similarly the Tecra lineup could benefit from a Blu-Ray-capable optical drive as an option.

One accessory that this could benefit from is a DisplayPort – HDMI adaptor so that people can be able to use common LCD and plasma flatscreen TVs like those at home or in hotels as external monitors.

This Tecra series has become a chance for Toshiba to make a bridge computer like the Fujitsu LH772. This is where they could use some of the Tecra features like the fingerprint scanner but have different colourings, making it appeal to the student market.

Conclusion

I would position the Toshiba Tecra R950 as an up-to-date work-home laptop for most small businesses. It has the security where-with-all and the extra RAM and hard-disk capacity that the small-business owner would need. The Bluetooth 4.0 interface allows this computer to work with battery-operated Bluetooth devices that can run a long time on cost-effective batteries or work with Bluetooth sensor devices.

II was choosing amongst the packages available, I would prefer this model for most users and the model below (4Gb RAM, i5 CPU) for those on a budget such as students. The Radeon-equipped variants would work well for users with graphics and multimedia creation needs or, perhaps, intense gaming. All along, I would focus on the 640Gb HDD as requirement for capacity.

Click to view: Samsung’s latest video / TV ad for the Galaxy S 3

My Comments

Just lately, as Apple were launching the iPhone 5 and the fanbois were lininig up outside the Apple Stores or mobile-carrier outlets to be the first to get this phone, Samsung have been running a video campaign about how more advanced their phones are compared to the Apple product.

Previously, I touched on Android’s competitive-environment abilities such as the use of other browsers or ability to shift content to the phone using the computer’s file system. This has also underscored the ability to provide paths to innovation that we are seeing in devices that work to this platform. The commercial that I am referring to, along with other Samsung TV commercials for the Galaxy S3, even emphasised the near-field communication technology as a content-transfer technology rather than just as an authentication technology, thanks to Android Beam.

Similarly, the latest crop of Windows-based computers that appeared over the last few years are showing that this operating environment is still a breeding ground for innovation. One key feature that we will be seeing more of is the touchscreen on these computers, most of which will have this feature work alongside a supplied or standards-compliant optional keyboard. I even reviewed a taste of things to come when I reviewed the Sony VAIO J Series all-in-one desktop. This was also augmented when I heard of a Toshiba Ultrabook that was to come with an NFC, which could support file transfer in the Android Beam manner.

This is showing that there are other companies and IT operating platforms out there who can make and improve the technology that maintains the “cool factor” in its use, rather than only one company with its platforms. It is the sign of healthy competition when this kind of innovation takes place.

Introduction

Yesterday, I attended the Symantec Symposium 2012 conference which was a chance to demonstrate the computing technologies Symantec was involved in developing and selling that were becoming important to big business computing.

Relevance to this site’s readership

Most solutions exhibited at this conference are pitched at big business with a fleet of 200 or more computers. But there were resellers and IT contractors at this event who buy these large-quantity solutions to sell on to small-business sites who will typically have ten to 100 computers.

I even raised an issue in one of the breakout sessions about how manageability would be assured in a franchised business model such as most fast-food or service-industry chains. Here, this goal could be achieved through the use of thin-client computers or pre-configured equipment bought or leased through the franchisor.

As well, the issues and solution types of the kind shown at this Symposium tend to cross over between small sites and the “big end of town” just like a lot of office technology including the telephone and the fax machine have done so.

Key issues that were being focused were achieving a secure computing environment, supoorting the BYOD device-management model and the trend towards cloud computing for the systems-support tasks.

Secure computing

As part of the Keynote speech, we had a guest speaker from the Australian Federal Police touch on the realities of cybercrime and how it affects the whole of the computing ecosystem. Like what was raised in the previous interview with Alastair MacGibbon and Brahman Thiyagalingham about secure computing in the cloud-computing environment, the kind of people committing cybercrime is now moving towards organised crime like East-European mafia alongside nation states engaging in espionage or sabotage. He also raised that it’s not just regular computers that are at risk, but mobile devices (smartphones and tablets), point-of-sale equipment like EFTPOS terminals and other dedicated-purpose computing devices that are also at risk. He emphasised issues like keeping regular and other computer systems up to date with the latest patches for the operating environment and the application software.

This encompassed the availability of a cloud-driven email and Website verification system that implements a proxy-server setup. This is designed to cater for the real world of business computing where computer equipment is likely to be taken and used out of the office and used with the home network or public networks like hotel or café hotspots. It stays away from the classic site-based corporate firewall and VPN arrangement to provide controlled Internet access for roaming computers. It also was exposing real Internet-usage needs like operating a company’s Social-Web presence, personal Internet services like Internet banking or home monitoring so as to cater for the ever-increasing workday, and the like. Yet this can still allow for an organisation to have control over the resources to prevent cyberslacking or viewing of inappropriate material.

Another technique that I observed is the ability to facilitate two-factor authentication for business resources or customer-facing Websites. This is where the username and password are further protected by something else in the similar way that your bank account is protected at the ATM using your card and your PIN. It was initially achieved through the use of hardware tokens – those key fobs or card-like devices that showed a random number on their display and you had to enter them in your VPN login; or a smart card or SIM that required the use of a hardware reader. Instead Symantec developed a software token that works with most desktop or mobile operating systems and generates this random code. It even exploits integrated hardware security setups in order to make this more robust such as what is part of the Intel Ivy Bridge chipset in second-generation Ultrabooks.

Advanced machine-learning has also played a stronger part in two more secure-computing solutions. For example, there is a risk assessment setup being made available where an environment to fulfill a connection or transaction can be assessed against what is normal for a users’s operating environment and practices. It is similar to the fraud-detection mechanisms that most payment-card companies are implementing where they could detect and alert customers to abnormal transactions that are about to occur, like ANZ Falcon. This can trigger verification requirements for the connection or transaction like the requirement to enter a one-time-password from a software token or an out-of-band voice or SMS confirmation sequence.

The other area where advanced machine-learning plays a role in secure computing is data loss prevention. As we hear of information being leaked out to the press or, at worst, laptops, mobile computing devices and removable storage full of confidential information disappearing and falling in to wrong hands, this field of information security is becoming more important across the board. Here, they used the ability to “fingerprint” confidential data like payment card information and apply handling rules to this information. This includes implementation of on-the-fly encryptions for the data, establishment of secure-access Web portals, and sandboxing of the data. The rules can be applied at different levels and affect the different ways the data is transferred between computers such as shared folders, public-hosted storage services (Dropbox, Evernote, GMail, etc), email (both client-based and Webmail) and removable media (USB memory keys, optical disks). The demonstration focused more on the payment-card numbers but I raised questions regarding information like customer/patient/guest lists or similar reports and this system supports the ability to create the necessary fingerprint of the information to the requirements desired.  

Cloud-focused computing support

The abovementioned secure-computing application makes use of the cloud-computing technology which relies on many of the data centres scattered around the world.

But the Norton 360 online backup solution that is typically packaged with some newer laptops is the basis for cloud-driven data backup. This could support endpoint backup as well as backup for servers, virtual machines and the like.

Mobile computing and BYOD

Symantec have approached the mobile computing and BYOD issues in two different paths. They have catered for the fully-managed devices which may appeal to businesses running fleets of devices that they own or using tablets as interactive customer displays. But they allowed for “object-specific” management where particular objects (apps, files, etc) can be managed or run to particular policies.

It includes the ability to provide a corporate app store with the ability to provide in-house apps, Web links or commercial apps so users know what to “pick up” on their devices. These apps are then set up to run to the policies that affect how that user runs them, including control of data transfer. This setup may also please the big businesses who provide those services that small businesses often provide as an agent or reseller, such as Interflora. Here, they could run the business-specific app store with the line-of-business apps like a flower-delivery-list app that runs on a smartphone. There is the ability to remotely vary and revoke permissions concerning the apps, which could come in handy when the device’s owner walks out of the organisation.

Conclusion

What this conference shows at least is the direction that business computing is taking and was also a chance to see core trends that were affecting this class of computing whether you are at the “big end of town” or not.

Article – from the horse’s mouth

Bluetooth Smart Ready product announcements piling up

My Comments

I have given some coverage about the new Bluetooth 4.0 “Smart” and “Smart Ready” technologies. These are improvements to the Bluetooth specification to allow the use of Bluetooth sensor and control devices that can work on low battery requirements – think 2-3 AA or AAA Duracells or a “watch” battery – for in an order of six months or more.

This has opened up paths for health and wellness devices like blood-pressure monitors, glucose monitors and pedometers. Even the old 80s-style digital watch is coming back with a vengeance as a smartphone accessory due to this technology.

Most of the Bluetooth-equipped tablets and smartphones issued over the past model year or so are equipped with this technology fully with software support. But an increasing number of newer laptops are equipped with Bluetooth 4.0 Smart Ready functionality at least on a hardware level and underpinned with OEM software. An example of this is the recently-reviewed Fujitsu LifeBook LH772 which has this interface.

These units would have full inherent implementation when they run Windows 8 and it could open up questions about how the Bluetooth 4.0 Smart technology could be relevant to the laptop or desktop “regular-computer” device class.

One way I would see it being relevant to this class is the availability of Bluetooth wireless keyboards, mice and game controllers that don’t need special rechargeable batteries to operate. Here, they could run for a long time of use on just the two or three AA batteries.

Sensor devices like temperature or humidity sensors that are important to particular profession or hobby groups like refrigeration / HVAC engineers or gardeners could benefit from this technology especially when used with a laptop or tablet. Here, these computers could work with data-logging software to record trends or monitor for abnormal conditions.

At least what is being proven with the current crop of Bluetooth-Smart-Ready capable regular and mobile computer devices is that the world of innovation with this low-power wireless netowrk is being opened up.

Introduction

I am reviewing the Dell XPS 13 Ultrabook which is Dell’s main foray in to the  Ultrabook thin-and-lignt market. The model I am covering is the more expensive unit which has a 256Gb solid-state drive

There are economy model of this computer, one with Intel i5 processor and 128Gb solid-state drive as the cheapest option and another mid-range model with an i5 processor and a 256Gb solid-state drive.

The computer itself

Aesthetics and Build Quality

Like other Ultrabooks,, this Dell XPS 13 is very light and doesn’t take up much room in your shoulder bag. The unit is wrapped in an aluminium finish with the keyboard surrounded in a rubber-feel panel which doesn’t feel as sweaty to use.

At times the computer does feel warm underneath after a long session of use. This is more noticeable around the back edge and is more so if you are engaging in video-heavy or CPU-heavy tasks.

User Interface

The Dell XPS 13 Ultrabook is equipped with an illuminated keyboard. But this keyboard does feel hard and has that cheap calculator-keyboard feel.  At least you can still touch-type on the keyboard easily. It als misses distinct keys for page-up / page-down functions which can be confusing when you are browsing a Web page.

The XPS’s trackpad doesn’t have distinctly marked-out buttons for selecting or confirming the options. This is similar to what is accepted on the MacBook computers and  it can be hard to locate the correct buttons by touch when you need to click or right-click that option.

The trackpad doesn’t respond to the double-tap = select gesture which is a common gesture for nearly all laptop trackpads.

Audio and Video

Right hand side connections – USB 2.0 port and DisplayPort

The Dell XPS 13 Ultrabook performed properly, responsively and smoothly with video content. This included action content that I viewed as part of a video-on-demand show. It may not be all that suitable for some activities like intense gaming.

I used this Ultrabook with the previously-reviewed Turtle Beach headset and found that you need to enable the Realtek Waves MAXXAudio all the time to keep “punch”in the sound even for the TV show. Of course, I would not expect much for the integrated speakers especially if you want to play music or desire movies and games with the effects being there.

Connectivity, Storage and Expansion

Left-hand side connections – power, USB 2.0, 3.5mm audio input-output jack

The Dell XPS 13 is equipped with two USB 2.0 connectors, a 3.5mm audio input-output jack and a DisplayPort port for monitors and video adaptors. These are its only connectors, in order to achieve a very slim notebook.

This Ultrabook has a 256Gb solid-state drive as its secondary storage and, unlike mist laptop computers that I have used or reviewed, doesn’t come with a memory-card slot. This would be considered an omission for those of us who take the memory card out of our digital cameras as part of transferring our images to a computer.

Battery life

The battery does live up to the expectations for an Ultrabook’s battery with it being half-empty aftar a good afternoon’s worth of hotspot surfing.

Even viewing 1.5 hour’s worth of on-demand video had the battery meter registering 45%. Like the Acer Aspire S3 Ultrabook, the Dell XPS 13 doesn’t support a hibernate mode for whenever you are not using the machine. Instead, the computer will stay in a “sleep mode” for a few hours then enter a “deep sleep”mode until you power it on.

Limitations and Points Of Improvement

The Dell XPS 13 Ultrabook could benefit from a pair of USB 3.0 sockets rather than USB 2.0 sockets so as to take advantage of external USB hard disks. As well, it could be equipped with an HDMI socket or be supplied with an HDMI adaptor so that it can connect to just about every flatscreen TV in circulation.

As I have said before, it definitely misses the SD card slot which would be important with digital-camera users who prefer to “remove the film” from the digital camera and this could be installed in the lid if you needed to balance out the space for the various hardware parts..

Conclusion

I would recommend that people purchase the Dell XPS 13 Ultrabook as a secondary notebook computer to use while travelling or using your favourite cafe, bar or hotel lounge as your second office. This assumes that you have a larger laptop or desktop as your main computer where you do most of your work on. It could be sold for a bit cheaper based on the options that it has even though the solid-state drive is sold at a premium.

Also, I would recommend that people who have digital cameras purchase an SD card reader if you you need to remove the card from the camera to download pictures. As well,you would need to know where the computer is at all times because the machine isn’t equipped with a lockdown slot.

Introduction

I am reviewing the Fujitsu LifeBook LH772 Series notebook computer which is what I would describe as being a “bridge” notebook computer.

This is where it is a 14” notebook computer that offers what is expected of a 15” mainstream laptop computer with such features as a large hard disk, a DVD burner, plenty of connectivity amingst other things.

Some of you guys may be shocked at my reviewing a pink-coloured laptop but it is available in a white or black colour as well as this pink colour. As I had mentioned with the Toshiba Satellite L730 that I previously reviewed, the white colour may also appeal to those of you who customise a portable computer by applying lots of decals on it.

For those of you who are interested, this notebook is the first one that has passed HomeNetworking01,info to be equipped with the Intel Ivy Bridge processor chipset which has quite a few benefits like improved integrated graphics abilities and integrated USB 3.0 support.

The computer itself

Aesthetics and Build Quality

This pink-coloured iteration of the Fujitsu LifeBook LH772 is finished in something that makes you think of neapolitan ice-cream where there is the pink body and the white keyboard.

It is a well-built computer with felt panelling underneath. This would make it less likely to slip on most furniture and make it more acceptable on that good French-polished dining table.

As well, through the times I have used this Fujitsu laptop, I have noticed no overheating even though there is a vent on the left hand side of this notebook.

User Interface

The transparent trackpad and trackwheel set in the acrylic finish alongside the buttons and fingerprint reader being obvious

The keyboard has that hard feel about it but you can still touch-type easily on it. There is also a full numeric keypad which would come in very handy for accounting and similar applications.

The trackpad and trackwheel are easy to locate by feel although you see a distinct square and circular area in the palmrest. As for the fingerprint reader, it is also easy to locate by feel and is very accurate under varying conditions including different temperature conditions or after I was eating some greasy food.

Audio and Video

Right hand side – DVD burner, 2 x USB 3.0 sockets

The Fujitsu LifeBook LH772 has the dual-mode graphics with Intel HD integrated graphics as well as NVIDIA GeForce discrete graphics. But this uses the NVIDIA Optimus automatic mode-switching facility so you don’t have to wory about whether you are using discrete graphics for performance or integrated graphics while on battery.

Left-hand side – VGA connector, 3.5mm audio-in jack, 3.5mm audio-out jack, 2 x USB 3.0 ports

This has yielded a smooth visual experience with on-demand video as well as regular computer use. One letdown with the display is the use of a glossy screen, which can be limiting if you have to dim the display to conserve battery life or have to deal with difficult lighting.

The Realtek sound subsystem had yielded the same “punch” when I watched a drama via video-on-demand and listened with headphones. The Internal speakers sound very similar to a  typical large portable radio or speaker dock especially when they play music. Of course, gaining a sound that has life in it from a laptop’s integrated speakers will be a difficult exercise due to the way these machines are designed.

Connectivity, Storage and Expansion

Rear view – Gigabit Ethernet port, HDMI port

The Fujitsu Lifebook LH772 has all the expected connections for a “bridge” notebook with VGA and HDMI video output, 3.5m audio input and output jacks, a Gigabit Ethernet jack and, best of all, 4 USB 3.0 ports. This makes me think that this notebook is future-ready as we connect more devices like 4G USB dongles and external hard disks to these computers.

The Wi-Fi wireless ticked the boxes as far as connectivity is concerned and there is a proper slide switch to enable and disable it for when you are flying. The Bluetooth subsystem is compliant to the 4.0 specification which allows it to work with sensor and controller that are required to work on a “watch” battery or 2 AA batteries for a long tine. This would work well for someone like a repairman who is using a Bluetooth 4.0 Smart thermometer to log the temperature of a fridge or air-conditioned space to check for efficiency or the behaviour of the thermostat.

The review sample came with a 750Gb hard disk and a DVD burner which would make it suitable as a main or sole computer for most people, rather than a secondary computer. As well, there is an SDXC card reader for downloading pictures from that digital camera.

Battery life

The battery can last the day with regular use including hotspot-surfing .

The long-lasting battery can allow the Fujitsu to work well for a long day of hotspot surfing at inner-city cafes and bars

It was able to play a DVD continuously for 4 hours, 15 minutes with the Wi-Fi and Bluetooth wireless subsystems running. It would be considered average for laptops that implement the dual-mode graphics technology and fall back to the newer Sandy Bridge or Ivy Bridge integrated-graphics technology while on battery power.

Limitations and Points Of Improvement

One key limitation that may come about here is the price and availability of this series. I would like to see  some lower-price and mid-price configurations with the i5 processors and lesser hard disk, but available with all the different colours. Similarly, Fujitsu could also run with a fourth colour like a blue or bronze colour if someone wanted that “manly-looking” colour.

Conclusion

This Fujitsu LifeBook LH772 series has become, in my honest opinion, a viable 14” bridge notebook option that could be targeted at people who work from home and like the idea of a portable computer that can connect to an external display or many other applications where this class would appeal.

The third-generation Intel chipset and the NVIDIA discrete graphics with Optimus mode shift can allow this computer toe work well with most games, video playback and most image-manipulation tasks. It is also a representation of a laptop that is brought to the latest hardware standards like USB 3.0 and Bluetooth 4.0 Smart Ready and can take advantage of these when the time comes.
