"Sony Ericsson launched its 12.1 megapixel Idou at Mobile World Congress yesterday evening, and while not a finished device, we checked it out anyway. The Idou will eventually roll with the Symbian Foundation's OS, but the version we're seeing here is somewhere in between. The resistive touchscreen (essentially the same as found on the XpressMusic 5800) is immense, glossy, and already brilliant. The transitions and sweeping gestures (check them in the vid) are really responsive and quick, with no real lag. We checked it against its nearest neighbor in the C905 and it is slim in comparison. Top notch stuff, we are anxiously waiting for more."
