I played with a HTC Touch device a few moments ago - it's beautiful!
It's slim, light, has a good battery life and a large vibrant touch screen plus 3G (thanks Arthur!) too. Its powered by Windows Mobile 6 so is easy to us and has a wealth of built in security features which Can be centrally managed.
This can be your phone, PDA, GPS (if you add a bluetooth receiver and software), music and video player AND it's shiney!
Sadly I don't have one...
