So far, from my limited testing of it, I'm pleasantly surprised. I can zip around applications and functions with one hand. The volume from the earpiece is actually fairly damned loud but this is coming from a first gen, first run Motorola V710 which was notoriously low earpiece.

Got to admit, now I know why these things are selling like hot cakes around New York City. A lot of function at an acceptable size. I can't wait till I can give it a real work out this weekend.
