What's Sony up to these days? Have they given up on the UMPC? I don't see any UX series on their website anymore. They even had some lingering UX models on the Sony Outlet. None left.
Maybe the next generation will be called the UZ series? It would be great if they develop something even slimmer than the UX. What if they took the PSP and added a touch screen and a sliding keyboard? Would that be the optimal form factor?
