VGN-U
Overview
The Sony VAIO VGN-U was a line of subnotebooks sold by Sony from May 2004 to February 2005. 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 two Sony VAIO computers that had a transflective display (the other one is 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).
Moreover, 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.
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.
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.
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, 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'll 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.
