My comments

I have covered the concept of expansion modules a.k.a docking stations that connect to laptops via USB 3.0, Thunderbolt or other similar connectivity as a must-have accessory. This is to allow people who use smaller or less-equipped laptops like Ultrabooks to use other equipment like optical drives or larger displays at their normal workspaces yet be able to maintain the portability of these machines. I cited this kind of device when I reviewed the Sony VAIO Z Series ultraportable which came with one of these modules that housed a slot-load Blu-Ray optical drive.

Lenovo issued one of these USB 3.0 modules as the ThinkPad USB 3.0 Dock. This unit had a Gigabit Ethernet connection as well as an external sound module and self-powered USB 3.0 hub for five devices.

Now ASUS have issued an improved USB 3.0 variant of a USB docking station that they previously released. The previous iteration had USB 2.0 connectivity therefore having access to 10/100 Ethernet, VGA and DVI video as well as an audio module and USB self-powered-hub connectivity for four devices. The video is supplied to the module using the DisplayLink video-over-USB technology to transfer the video to the VGA and DVI ports.

Now this improved version satisfies the current expectations by being equipped with a Gigabit Ethernet port as well as an HDMI port for current displays. This has the audio module and the USB 3.0 hub but uses the latest iteration of the DisplayLink technology to exploit the high throughput of USB 3.0 for high-resolution displays and stereo or surround-sound audio via HDMI. It is infact the first USB 3.0 docking station or expansion module that I have heard of that implements this DisplayLink setup.

Personally, I would like to see this device and the previous version equipped with an SP/DIF optical output using the same 3.5mm optical-electrical jack that Sony used with some of their CD Walkmans in the mid-90s to facilitate digital CD-MiniDisc recording with their MD Walkmans. Here this connection could be used provide a high-quality PCM stereo or bitstream surround digital signal to amplifiers that have built-in digital-analogue conversion circuitry.

As long as these are kept to common standards, it could then be feasible to supply the expansion modules to work with extra peripherals at one’s main work locations.

My Comments

I have previously talked about on this site about the concept of standards-common expansion modules for use with laptops, especially Ultrabooks. These devices, also known as docking stations, would have connections for peripherals that you would typically used at your desk like larger displays, Ethernet network connections or work-specific peripherals.

Infoact one of these devices was part of an ultraportable laptop that I had reviewed, namely the Sony VAIO Z Series unit; and this one included a slot-load optical-disc drive that reads Blu-Ray Discs.

Now Lenovo have presented the ThinkPad USB 3.0 Dock, which connects to the host laptop using a USB 3.0 connection, already common on most laptops including higher-priced Ultrabooks. But it exploits the higher data throughput of USB 3.0 to allow for more than what one would typically expect from these devices.

For example, the expansion module is a network adaptor for Cat5 Gigabit Ethernet networks and an external sound module as well as a self-powered USB 3.0 hub for five peripherals. The self-powered USB hub also has the advantage of supplying power to USB peripherals independently of the host computer so that you could charge up smartphones and other gadgets or use it as a power supply for USB-driven gadgets.

But it uses DisplayLink technology to use the USB 3.0 connection to drive external displays while using the host computer’s graphics subsystem. This can encourage us to use the large displays with these laptops without needing to connecting them to the computer itself.

What I would like about this expansion module and any expansion modules designed along this line is that it isn’t dependent on the laptop being a Lenovo ThinkPad model at all, let alone a Lenovo unit. Compared to the Sony solution which exploited a proprietary “Light Path” setup over USB 3.0, this could be used with computers that use any USB 3.0 port.

This is more so as the next generation of Ultrabooks come with USB 3.0 ports integrated in to them but may have two or three of these ports as well as fewer connections for other wired peripherals. Infact the more of these devices that exist, the better it would be for people who use “work-home” laptops or 13” ultraportabls as travel/desk computers/

Product Review–Sony VAIO Z Series premium ultraportable computer (VPC-Z217GGN)

Introduction

I am reviewing Sony’s VAIO Z-Series which is their top-shelf ultraportable computer and a model that courts the Apple MacBook Air or the high-end Ultrabooks. This gold-finished variant uses a “split-personality” setup where it can gain extra functionality through a supplied docking station that houses discrete graphics, a power-supply and what’s more, a slot-load Blu-Ray reader / DVD burner.

The computer itself

The Sony VAIO Z Series is available in two versions – a gold-finished variant which is supplied with an extended-functionality “docking-station” unit a cheaper black-finished unit which has the docking-station unit available for AUD$699 extra

This docking-station unit has the AMD Radeon discrete video chipset as well as a Blu-Ray reader / DVD-burner drive in it and has a Gigabit Ethernet connector and two USB connectors on it. It connects to the computer using a single cable that plugs in to the right-hand side, where it can also power and charge the computer. Here, you have to make sure you press an “undock” button on the plug and wait for a blue light to turn off before you unplug this plug. It even stands on a gold-plated vertical stand which emphasises the market position that this computer is targeted for.

Aesthetics and Build quality

The VAIO Z Series aesthetics is very similar to a lot of the 13” “thin-and-light” ultraportables and the “champagn-gold” finish for this model that I am reviewing makes it look the part even in a business hotel’s lounge. There is still the good build quality associated with all of the Sony VAIO computers in this model.

As for overheating, the computer is well-ventilated to avoid this problem and the use of integrated graphics and outboard discrete graphics cuts down on this problem.

User interface

The VAIO Z Series comes with an illuminated chiclet keyboard but the illumination is more subtle than most similar implementations, more like what you see with luminous watches. It can still allow full touch-typing but could benefit from the home keys being made easier to find by feel and the keys have the hard-plastic feel about them.

The trackpad has a rough-textured area to move the cursor with and smooth-textured selection buttons. This makes it easier for one to operate the Sony VAIO’s trackpad by feel.

Audio and Video

Here, it would work with the Intel HD integrated graphics in a standalone environment or, if it is connected to the Blu-Ray module, it can work with an AMD Radeon discrete chipset in that module. The USB 3.0 link allows the use of the laptop’s screen and video connections or the video connections on the Blu-Ray module.

The setup that Sony has worked on for the VAIO can let it become a high-flying high-performing laptop for business, gaming and beyond as well as a battery.conserving laptop for basic tasks on the road.

glossy screen which may be of concern in bright environments  but the darker bezel surrounding the screen does make for improvements in improving the display’s legibility.

The audio subsystem is different in that it just uses the Intel HD audio chipset whether on the Blu-Ray module or standalone. The internal speakers are likely to distort on high frequencies too easily and this can be a problem with smaller laptops. I would improve on this design with a discrete sound subsystem like Creative Labs SoundBlaster in the Blu-Ray module and fit audio inputs and outputs to that module for better sound quality.

Connectivity and Expansion

The idea of the docking station that is part of the VAIO Z Series has permitted Sony to provide a highly-functional computer which suits different applications. Here, you have one USB 2.0 and one USB 3.0 connector on the computer as well as the VGA and HDMI video outputs and Ethernet socket. But this level of connectivity is replicated on the Blu-Ray docking station with the ability to connect peripherals to both devices.

The USB 3.0 port can be set up to provide charging power for gadgets when the laptop is off in a similar vein to what the Toshiba laptops that I reviewed offer.

Battery life

The battery is able to last for around five hours of continuous stand-alone use due to the laptop using just the integrated display in that mode. If it is playing optical discs, it would be done on external power due to the Blu-Ray external module becoming the laptop’s power supply.

Limitations and Points Of Improvement

Lid view

One point of improvement that I would see for the VAIO’s Blu-Ray docking modules would be to enable one or all of the USB ports on the docking station to be powered charging ports. This is irrespective of whether the laptop is connected to the docking station or not, so as to allow one to power or charge a mobile phone or similar gadget from this device at all times. The function could be selectively enabled through the use of a hardware switch on the side of the docking module.

Similarly, the Sony’s docking module could house an advanced audio subsystem like Creative SoundBlaster and have audio connections to allow the VAIO to yield Sony’s high-quality audio standards with a nice set of speakers.

For that matter, the idea of an advanced-function docking station that Sony implemented with the VAIO Z Series could be taken further with a micros hi-fi system, home-theatre system or AV component that integrates this functionality in the same chassis. Sony could then take this concept across all of the VAIO “thin-and-light” computer series and use a connection like the new “Thunderbolt” connection for these enhanced-functionality modules.

A cheaper “Fairlane-grade” variant of the Z Series black-finished variant could benefit from a 320Gb regular hard disk that is assisted with a 20Gb solid-state drive implemented for quick-start behaviour. This is becoming a trend for some of the Ultrabooks so as to provide for lower price points and granular model lineups.

Conclusion

Sony VAIO Z Series ultraportable

Doesn't look out of place in that business hotel's lounge

The prices that are set for the Sony VAIO laptop make it appealing for the “Rolex-class” of businessman who wants an ultraportable that shows the wealth. But the concepts that are espoused in this model could be implemented in the Ultrabook class of thin-and-light ultraportables.

It may be worth thinking that If I were to buy the black version of this model, I would use the docking-station module that is optional for that model as leverage for the deal.
