Cons: Very thick and bulky; Single mini-USB port for charging and headphones; I still don't like Windows Mobile
Sprint's Touch Pro is a little longer and wider, but also a little bit thinner than AT&T's version ("Fuze"). Sprint also eschew's the original Touch Pro's all black & faceted back design for a silver on grey color scheme and a rounded back panel.
Otherwise, it's Touch Pro in all of its WinMo 6.1 Pro, TouchFlo 3D, VGA touchscreen and slide-out QWERTY board glory. The phone tends to run a bit hot to the touch under heavy stress, and nobody would ever call it "thin," but it's a total beast that Sprint spiced up with their own mobile TV and Music Store offerings.
In my own side-by-side tests at the PhoneDog West offices, Sprint's Touch Pro grabbed data slightly faster than AT&T's Fuze, as well. So if you're planning on a lot of 3G Web surfing in the Berkeley, CA area, you might look to Sprint before AT&T for your Touch Pro fix.
Verdict: Thumbs Up
