Looking for a tablet UMPC

I’m in the market for a tablet UMPC. I already have an HP Pavillion tx1308nr tablet notebook that’s pretty good after I upgraded the ram to 2GB. I need something like my HP but portable. I was thinking of the Sony UX but I don’t want to pay $2000. I’m leaning towards the Fujitsu U810. I would mainly use it to answer emails and design Baybayin while on Bart. I just read that a U820 is coming out soon but I don’t know when. I bet it will be $$$$. Too bad the Asus EEE PC does not have a tablet…..yet.
