Hey guys, thinking about buying a Touch...looking for the answer to some questions. 1. How smooth is the interface when you are playing music and on Safari? 2. Has anyone used one of the Safari-based AIM connections (like FlickIM?) on Touch? Does it work as well as it works on the iPhone? 3. Does it lock up often? I bought one of those Motorola-iTunes ROKR phones back in the day, and the interface was choppy and locked up all the time.
