The new Treo600 seems about five times faster than Treo270 at doing searches etc which is very useful when you have a large database of names and messages etc (Treo270 typically took over 30 secs to search my database). The buttons feel much smaller and closer which makes pressing the option key and search key tricky, but just possible, for my 'shovel' hands. The keyboard is in fact (22% smaller in area).
