The experience doesn't get that much better. I've been using it for 5 years. Data speeds have greatly improved, especially with EVDO Rev A. Keypads today are barely better than the Treo 650's. Apple's made some definite strides in making the touch screen usable (far beyond the old Palms) but it's still vastly inferior to a 19" LCD and a mouse, and improvements will now come incrementally.
