I tried out a friends Touch yesterday. I like the flush screen which is key to using the gestures and even full use of the keyboards lower register of letters, but in addition it has a different feel to it, almost like it feels harder and more glass like than most other PDA screens. It is still not as responsive (for finger taps) as the iPhone, but it is much better than any PDA phone I have tried. Not worlds better mind you, but for how often I need to use an on screen keyboard, it will do.
