If this is legit, color me impressed and intrigued. The Unofficial Sony Ericsson Blog posted what they're calling an exclusive demo video of Rachael's UI, Rachael of course being the codename for SE's forthcoming first Android phone. Whatever's in the vid, be it the actual UI or a fanboy's cartoon dream, looks great - a rather HTC-like custom UI with eye-pleasing apps for messaging, twitter, music player, and so on. The Xperia-branded Rachael is said to be on tap for launch later this year, and will be built on the Snapdragon platform and feature a crazy-big display measuring no less than four inches diagonally.
