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.
