When I swapped my XPRT for the Admiral and the sensitivity of the Admirals touch screen was the one thing that bothered me in the beginning. It's almost as if you have to press just a fraction of a second longer to scroll as compared to other devices. (Which, btw, is exactly what former Nextel users seem do when using a touchscreen for the first time) Now after two weeks, I don't even notice it.
The fact that this phone has the best keyboard I have ever used (excluding the Blackberry Bold 9650) made that two week learning curve worth it.
