Has anyone upgraded from RT to Pro, I took the opportunity today to test out a RT in a UK store today and was really disappointed. Maybe my expectations were too high, a friend of mine has a Samsung slate 7, which he put windows 8 on, and that is really good to use. I found that RT was really slow, in opening apps, lot of gestures and movements didn't register, you have to be pretty heavy handed and repeat swipes to get it to work. The touch keyboard I did not get on with whatsoever, maybe I had a defective unit perhaps?. Hopefully someone can tell me that the pro is totally different to the RT, for the user experience and I can relax, I know the spec for both and what they are both aimed at, more interested in the user experiences. The Pro hasn't been released in the UK yet, so got a while to make up my mind on what to do.
