The Sony U-series of subnotebook computers refers to two series of Sony products the PCG-U and the VGN-U . The later VGN-U were, at their release, the smallest independent computers running Windows XP and the most powerful high-end subnotebooks at the time. The VGN-U50 and VGN-U70P models are 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 is the VGN-U750P. A VGN-U8G model was introduced for some south Asian countries. ==Technical specifications== Additional Specification for VGN-U Series * Display: 5 in (127 mm) SVGA, 800×600, 16 million colors, touchscreen * Keyboard: 87 keys, English/Japanese layout (connects via USB, does not attach to unit) * Expansion ports: * *Sony Memory Stick * *CompactFlash Type-II (can be used as 16-bit PCMCIA with proper adapter) * Soundcard: PCM 16-bit audio, mono speaker, stereo headphone jack * Mouse: TrackStik (trackpoint-like) with 2+1 buttons (left, right, middle) * Handwriting recognition software: RitePen; also compatible with third-party alternatives such as PenOffice Other: * LCD for headphone remote, time display * 1 USB 2.0 Port * Power supply: AC 100/240 V (50/60 Hz) – DC 16 V/2.2 A/?
