I am now reviewing the Sony VAIO P-Series netbook. This is a computer that is of a similar size to a chequebook wallet of the kind that many busy women like to keep in their handbags. The review sample cam in a bright orange colour but is available in blue or white. All of the units have a black bezel around the display and as a strip above the keyboard as a common feature.

This review unit’s colour scheme reminded me of a similar colour scheme used by Electrolux on a vacuum cleaner sold on the Australian market in the early 1970s where the unit was this same orange colour with black trim.

The computer itself

Because the computer is intended as a personal portable computer that is intended to be small and run for a long time on batteries, the specification set will be very minimal, alongside that of a low-end netbook.

Processor and RAM

Like other netbooks, the VAIO P-Series computer is based around the Intel Atom processor which is pitched at this class of computer. It works on 2Gb of RAM with some being used for display memory.

Display

The display is powered by an Intel Graphics chipset and appears on an 8” widescreen LCD display. This can be a limitation for any long-term computing activity due to the way regular-sized fonts come up on this display. It will then require the user to adjust the “dots-per-inch” setting in the Display menu in Windows Control Panel. You may alos have to use Windows Magnifier and / or reduce the number of toolbars running in Web browsers and similar applications.

Keyboard and pointer control

The keyboard uses a “chiclet” style and may look similar to some of the “pocket computers” of the early 1980s. The unit also uses a “thumb-stick” mouse similar to what has been commonly used on IBM / Lenovo laptops with the primary and secondary “click” buttons under the spacebar.

Secondary storage

The VAIO uses a 64Gb solid-state drive which is based on flash-memory technology as its primary secondary-storage space but there is a memory card reader that works with SDHC and Memory Stick cards available for removeable storage.

Connectivity

There is wireless connectivity for 802.11g/n Wi-Fi networks as well as Bluetooth peripherals, which would appeal to this computer’s user base.

Peripheral connectivity is limited to two USB sockets (which you may have to use one of for a 3G wireless-broadband modem) as well as a headphone socket for audio playback applications. There is a dongle that connects to a special I/O connector which provides for connection to Ethernet networks or VGA displays.

Observations

During the review period, the woman of the house had shown some interest in this computer because of the orange housing and had wanted to wish-list it to her husband. She also had use of the machine to type up a test document and browse her Web-based email account and found that it can be cramped but was enamoured about it as a “handbag companion PC”.

Limitations and Points of Improvement

One main point of improvement that could be provided for is the default use of a desktop setup that allows for readability on this display. The computer could also benefit from being provided with an integrated 3G wireless-broadband modem with software mobile-phone functionality, which could make it attractive to mobile-phone carriers to sell at a subsidised price with a 3G service plan.

Conclusion and Placement Notes

The small display and the large price tag may put this machine out of the reach of most people. But some people who want a handbag-sized computer with a proper keyboard for doing contact management, e-mail, Web browsing on a fully-functional browser and similar activities may appreciate this unit.

UPDATE:  I have had to repost this review because something has happened with the site and the copy for the review has disappeared suddenly

I am reviewing the Dell Inspiron Mini 10 netbook which is the first computer of this class that I am able to review. It would be one of these machines that was considered the right machine to own during the heart of the Great Financial Crisis but still has a place in today’s home network as an auxiliary computer.

As with all Dell computers, you choose the specification for the computer when you order it through their Website and the specification that is available on the Website may differ from the one that I am reviewing. The base specification for this computer would cost AUD$449.but there are more expensive specifications available that primarily have the computer prepared for wireless broadband or an onboard TV tuner.

The netbook computer itself

The computer is finished in an “Apple-white” gloss finish on the outside and black around the keyboard and screen escutcheon. The gloss finish may still have the disadvantage of attracting fingermarks during regular use. There isn’t anything that can appear to damage good dining-room tables when the machine is placed on these tables.

My review sample is outfitted with the Intel Atom netbook processor and works with 1Gb of RAM, some of which is shared with the display memory.

The secondary storage is based around a 160Gb hard disk as single logical drive and an SD card slot as removeable storage. The computers that come through the Website will have 250Gb hard-disk space.rather than the 160Gb that is part of the test specification.

The graphics infrastructure is based around an Intel graphics chipset that is optimised for netbooks and yields a 1024×600 resolution on the 10” screen. The only external display connectivity available in this case is a VGA socket.

As well, there are three USB sockets – one on the right-hand side and two on the left-hand side.There is also an Ethernet connection for wired networks and the audio in-out jacks on the right hand side. For wireless connectivity, this unit supports Wi-Fi to 802.11g as well as Bluetooth wireless.

The operating system used in this test specification is the Windows XP Home Edition SP3 but computers that are available for sale come with Windows 7 Starter Edition. It may be still worth upgrading the operating system to Windows 7 Home Premium through an Anytime Upgrade pack if you want better network functionality.

Observations and Experiences

The keyboard is responsive but may appear cramped due to the small size of these computers. The touchpad is very small but works well for navigation. These are situations that are considered typical for computers in its class.

I had watched a few YouTube videos about IT and found that the computer is still good with downloaded video content. As well, I had run it through a round of an action-puzzle game on MiniClip which is a popular casual-game site, and the game was still very responsive. Obviously this wouldn’t be the kind of computer for playing the big-time games but would be good for casual games and similar use.

I haven’t worked out a battery “drain test” yet that is appropriate for computers of this class but as I was working on the computer which was running on batteries, I kept observing the battery meter as I used the computer even while I had McAfee do a virus scan in the background and Windows Update deploy the latest set of updates to XP, the computer doesn’t look like it goes tbattery quickly. I also made these observations with the computer under manufacturer-default conditions.

Conclusion and Placement Notes

I would place this computer as a unit that would be useful as a small-size auxiliary computer for travelling or use around the home such in the kitchen or “Facebooking” in front of the TV. It may work well as something with a keyboard for getting notes on to a file while out and about before you “finish” them on your main computer.

Hitachi-LG teases HyDrive: an optical reader with loads of NAND (video) – Engadget

My comments

The main thing that impressed me about this was that both the tray-load optical drive and the solid-state drive wore integrated in to the same low-profile chassis that would suit installation in to a laptop. There are many benefits that I see with this.

One would be that you could have a laptop specification that has both a large-capacity hard disk that is used for data and a lower-capacity solid-state drive used for the operating system and applications. It could then allow for battery economy and quick starts while the high capacity on the hard disk can exist for the user’s data and this hard disk is only spun up when the user’s files need to be loaded or saved.

As well, if Hitachi and LG move towards higher solid-state capacities, this could allow for low-profile laptops like the “thin-and-light” segment to have the SSD as the main system drive while supporting an optical drive.

I am reviewing the Hewlett-Packard ProBook 4520s business-class notebook which may be the first such computer that has come across in this blog. It is one such machine that I am assessing as whether it fits the purpose of a “work-home” laptop for a small-business owner or not.

The unit I am reviewing has a recommended retail price of AUD$1299 but you may be able to get the the same specification for a bit less if you shop around. Cheaper models in this lineup would have a smaller hard disk, run Windows 7 Home Premium rather than Professioamnal, come with a standard battery which has a shorter runtime amongst other differences.

The laptop itself

The unit is finished in a brushed satin-bronze finish on top of lid and keyboard surround, but some variants have a dark-satin black finish. There is a a black screen escutcheon which also hides the Webcam for face-recognition security and Skype communications.

The large keyboard has a feature that is not seen on may laptop computers – a separate numeric keypad. This will please accountants and others who work with figures. It is of a “chiclet” square-key stile but is spaced enough so as to permit accurate touch-typing.

Laptop keyboard with numeric keypad

There is a multi-touch touchpad which may take some time to get used to for people who haven’t used this kind of control before. It has the primary and secondary buttons as part of the bottom margin in the same way that the HP Envy has for its touchpad.

It is powered with the Intel Core i5 processor “engine” and is supplied with 4Gb RAM with 1Gb set aside for display memory. The graphics “engine” is a highly-robust ATI Mobility Radeon HD 4350 series which would be good enough for most business tasks, even video playback.

The secondary storage options are on a par with a current-issue laptop of this class. It has a 500Gb hard disk with 1.8Gb partition for HP software. It also has a tray-load DVD burner that can label LightScribe optical discs and a memory-card reader for removeable storage.

You also get good things when it comes to connectivity with 3 USB ports and 1 eSATA external-disk port as well as an ExpressCard 34 slot for additional functionality. External displays can be connected using a VGA or HDMI connector.

Business software complement

The operating system for this laptop is Windows 7 Professional which is the version of Windows or7 I would recommend and have recommended in this blog for small business and professional use. It has the features of Windows 7 Home Premium plus other features that make it  business-friendly.

The unit is supplied with a very good business software complement with an inplace ready-to-enable distribution of Microsoft Office Professional, McAfee Total Protection web-managed desktop security software as well as WinZip 12. Hewlett-Packard have also put in their own branded system-protection tools which are developed by Digital Persona, which provide password management, facial-recognition, secure-erase, device-usage control amongst other things.

Observations and Ecperiences

The computer doesn’t run hot too quickly after extended periods of use, thus allowing it to be comfortabie to use. If it gets hot, the heat is passed out the left hand side rather than being felt on the bottom of the machine.

Its battery has a lump which can tilt the laptop up slightly also to allow better cooling and comfortable use. This lump has a rubber ridge to protect the good dining-room table but the design could extend to full width of battery for better protection

The extra-length battery that came with this machine allowed it to complete a feature move on DVD with Wi-Fi and Bluetooth enabled. Infact there was 41% of power available after the movie was completed and these tests were done with Windows Media Player playing “Munich” and the computer running on the HP-defined default power configuration. This then would mean that it could run a long time without you needing to look for a power

The other thing I also admired about this machine is that the metal finish keeps its look even if it is well used unlike a lot of the glossy finishes used on laptops that attract fingermarks and the like. It also feels cool to handle and is the kind of finish that would cope with long-time use.

Limitations and Points Of Improvement

The main limitation with this computer is that it is too heavy for frequent public-transport travel, which may cut it out for frequent air travellers. Some people may find that the long-run battery’s large size and lump may be a limitation for packing and could be improved with a battery that is more cell-dense.

Other than that, there aren’t any other limitations that would impact on its positioning as a business-home home laptop computer.

Conclusion and Placement Notes

I would recommend this as a business-home laptop or desktop replacement for professionals and small-business operators who are likely to take the unit between home and their place of work. It also comes with business-grade security software that is available at prices and licensing quantities that small business can stomach.

 Samsung Super AMOLED explained in pretty moving pictures (video) – Engadget

Samsung’s explanatory video clip

My comments on this technology

Same desirable attributes as the OLED displays, but improved in significant ways. Ability for the display to have integrated touch-sensitivity, This leads to slimmer touchscreen handsets which is an increasingly-important application in the now-competitive smartphone market, as well as similar applications like remote-control handsets and personal media players.

They have improved the outdoor viewing ability and display responsiveness for this display, which would be of benefit to mobile phones as well as digital-imaging and handheld-games-console applications. But do I see this technology going further? Another application that I could see the Super AMOLED work well with is a watch which works as an auxiliary display and control unit for mobile phones, like some of the Sony Bluetooth watches that have been surfacing lately. Such watches could then permit a colour display on the wrist with various interesting applications.

An area where this Super AMOLED technology could excel would be automotive and marine applications, especially if the cost of larger-area displays comes to a par with the common LCD displays. For example, the new multi-function displays that are becoming the control point for HVAC, infotainment, navigation, and similar applications in newer cars could move towards this display technology. Similarly, this technology could appeal to personal navigation devices a.k.a. “sat-navs” or GPS units, marine GPS / fish-finder units as well as aftermarket car-audio equipment.

What I see is that the Super AMOLED could be one of the next key display technologies as was the LCD or the LED displays.

Nokia and Alpine integrating handsets into cars, bringing Ovi Maps to your dashboard — Engadget

From the horse’s mouth

Alpine’s press release

My comments

Phones like this one can now let the Alpine blast

They have achieved this through “Terminal Mode” which uses a “gateway app” installed on the phone and the phone linked to the system through a USB cable or a Bluetooth link. The phone’s apps can benefit from the larger display found in high-end car-audio installations.

The reasons I am pleased about this technology is that

a) the mobile phone that links with a car stereo for full functionality doesn’t have to be the Apple iPhone

b) there is an incentive for vehicle builders, car-audio manufacturers and handset manufacturers to establish a level playing field for achieving full functionality for mobile phones from the dashboard.

This can also lead to further functionality like Pandora, Last.fm, Internet radio, location-based services and extended navigation becoming available at the dashboard without needing to use multiple applications installed in a phone platform that you don’t have or on your car’s infotatiment platform.

A few weeks ago, a young teenager friend of mine had the Kogan internet radio, which I previously reviewed a sample of and had bought, “tuned” to an Iranian pop-music station that was broadcasting via the Internet. This youth, who had just turned 18 and was about to get his driver’s licence, was asking whether Internet radio in the car would be a reality.

Issues that limit this concept

One of the main issues would be for the wireless-broadband standards like 3G and WiMAX to support media-streaming in a reliable manner and at a cost-effective rate. Recently, there were issues with AT&T raising concerning about Apple iPhone users drawing down too much data, especially multimedia and another 3G provider wrote in to their subscriber terms and conditions a prohibition against media streaming.

The main issues were how these networks handle real-time content and whether they can stream this content reliably when the vehicle is travelling at highway speeds or faster. This also includes how to achieve this cost-effectively without limiting users’ ability to enjoy their service.

One way that it could be mitigated would be for mobile carriers and ISPs to look towards providing “sweeter” wireless-broadband deals, such as integrating voice and data in to single plans. Similarly,the providers could optimise their services to cater fir this kind of use.

Ways of bringing Internet radio to the speakers

Internet radio functionality integrated in car audio equipment

In this setup, the car-audio equipment, whether as part of the in-dash “head unit” or as an accessory tuner box, has access to a TCP/IP LAN and Internet through a modem or an outboard router. It uses any of the common Internet-radio directories like vTuner or Reciva to allow the user to select any of the audio streams that they want to listen to.

Wireless broadband modem integrated in or connected to car audio equipment

The car-audio equipment would have a wireless-broadband modem integrated in the unit or connected to it. The latter situation could be in the form of a USB “dongle” plugged in to the unit, or a mobile phone that supports wireless broadband being “tethered” by USB or Bluetooth to the unit. If the setup involves an integrated modem or an attached USB “dongle”, the setup may use authentication, authorisation and accounting data from a SIM installed in the unit or “dongle”; or simply use the data from a phone that uses Bluetooth SIM Access Profile.

This practice had been implemented in a Blaupunkt car stereo which was being used as a “proof-of-concept” for Internet radio in the car.

Use of an external wireless-broadband router

This method involves the use of a mobile wireless-broadband router which has an Ethernet connection and / or USB upstream connection with a standard “network-adaptor” device class along with a WiFi connection. Of course, the device would have a wireless-broadband connection on the WAN side, either integrated in to it or in the form of a user-supplied USB modem dongle or USB-tethered mobile phone. A typical example of this device would be the “Autonet” WiFi Internet-access systems being pitched for high-end North-American Chrysler-built vehicles or the “Ford Sync” integrated automotive network available on high-end North-American Ford-built vehicles that gains Internet access with a user-supplied USB wireless-broadband dongle.

Here, the car-audio equipment would have a network connection of some sort, usually an Ethernet connection or a USB connection that supports a common “network interface” device class and would be able to “pick up” Internet radio as mentioned before.

Internet radio functionality integrated in an Internet-access terminal

At the moment, this will become the way to bring Internet radio to most car setups in circulations for some time. The setup would typically represent a mobile phone or laptop computer with an integrated or connected wireless-broadband modem. This would have software or Internet access to the Internet-radio directories and stream the audio through Bluetooth A2DP, an FM transmitter or hardwired through a line-level audio connection, a cassette adaptor or an FM modulator.

Increasingly, there is interest from car-audio firms and Internet-media software firms to establish an application-programming interface between a computer or smartphone running selected Internet-radio directory software and the car sound system. This would typically require use of Bluetooth or USB and use a control method of navigating the directory, in a similar manner to how most current-issue car-audio equipment can control an attached Apple iPod.

The primary platform where this activity may take place would be the Apple iPhone, because of it being the most popular programmable smartphone platform amongst the young men whom the car-sound market targets.The setup was demonstrated at the Consumer Electronics Show 2010 in the form of Pioneer and Alpine premium head units controlling a front-end app for the Pandora “custom Internet radio” service installed in an iPhone connected to the head unit via the special connection cable that comes with that unit.

On the other hand, if a smartphone or MID that is linked to the head unit via Bluetooth A2DP does support the AVRCP profile properly, an Internet-radio application installed on that smartphone could achieve the same goal. This would require that the directory applications are able to expose links to the AVRCP commands and requests.There will also have to be requirements to allow “source selection” between multimedia applications through the AVRCP protocol.

Further comments

This concept will become part of the “connected vehicle” idea which provides real-time access to navigation, telematics, communication and entertainment in a moving vehicle or craft, especially as companies involved in this segment intend to differentiate their offerings. It may also be very desireable as an alternative to regular radio in those areas where most regular radio broadcasts leave a lot to be desired.

Once the cost and quality of wireless broadband Internet is brought down to a level that is par with reasonably-priced wired broadband service, then the concept of Internet radio in the car will become reality.
