The Sony VAIO VGN-U was a line of subnotebooks sold by Sony from May 2004 to February 2005, which succeeded the PCG-U line and was the first "U" to be released outside Japan. At their release, they were the smallest independent computers running Windows XP and the most powerful high-end subnotebooks at the time, being roughly the size of two DVD cases stacked on top of each other.

The first models of the series to come out were the VGN-U50 and the VGN-U70P in Japan. The American model, the VGN-U750P, came out in December 2004. A two models for Asian markets were introduced as well, specifically the VGN-U8C for Chinese market and the VGN-U8G for Singapore.

The VGN-U lineup is also known as one of the only three Sony VAIO computers that had a transflective display (the other ones are the PCG-C2GPS but it had a separate backlight module making it more of a reflective display whereas backlight is built into the VGN-U display and PCG-U101, which has a truly transflective panel).

Detailed Specs

The VGN-U lineup had a total of 6 models, some of which either had minor differences or were rebranded versions of previous models for other markets.

The custom proprietary display of VGN-U is seemingly capable of refresh rates up to 85Hz; although the integrated GPU outputs 60Hz signal, the display panel likely uses a technology called motion interpolation to generate and insert frames between the real frames on the fly, thus smoothing any motion that happens on the screen. This theory is accompanied by direct comparison with the VGN-UX, in which screen on the VGN-U seems more smooth in operation.

None of the VGN-U models had a built-in keyboard. Instead, they had a separate Sony VGP-KBC1 Foldable Keyboard, the compact USB keyboard which resembles a laptop keyboard. It folds in the middle, and has a TrackStik mouse pointer in the center. When folded, the unit is approximately the same width and height of the U-series unit, and about half the thickness. Also, all models had backlit buttons on the unit itself, which could show various light effects when device is turned on, attempted to turn on while on hold or the screen is rotated using Rotate button.

Using a combination of bundled VGP-PRU1 Port Replicator, any USB keyboard and mouse connected to the Port Replicator (or just bundled VGP-KBC1 keyboard since it already has TrackStik), and any VGA monitor, user could essentially turn their VGN-U into a desktop PC while still retaining the portability: the unit can either divert display output to the VGA port or mirror the image, allowing for a convenient experience on a large screen, and can be undocked without turning the power off. Also, the Port Replicator will also charge the device's battery while it's docked.

It came with many accessories in the box, including the Port Replicator, Remote Commander (headphone remote control unit, which is the same type used by Sony in its MiniDisc players, making it quite easy to find, which allows one to control audio playback and read current track information), VGA/Ethernet dongle, stylus and pouches for the computer and the foldable keyboard.

Daily Usage Today

While extremely advanced for its size, especially back in 2004 (being the smallest full-featured PC running Windows XP in the world when it was released), all VGN-U models are almost completely useless from a practical point of use nowadays. Its processor has only one slow (by today's standards) core, 512MB of RAM is too little for modern tasks, and integrated graphics can't handle Windows Aero nor they have any WDDM drivers available. The 1.8" HDD is also quite slow (it uses the same compact IDE interface as Apple's iPods, so spares are easy and cheap to find, as well as flash modding solutions, however even if you manage to install a fast drive, you will only see an increase in random access speeds, while linear speeds will still be limited by low bus speed). The lack of built-in keyboard makes it hard for office use as well. However, you still can do very basic web browsing, but it is not going to be a very pleasant experience.

Overall, the VGN-U can only be recommended as a rare collectors item, and a rather expensive one as well, especially the VGN-U8C, VGN-U8G and VGN-U750P.
