I'm interested in the Google Voice functionality. It's one of the main reasons I'm switching from a Blackberry Curve. I've heard "seamless," but haven't seen it in action yet.
I'm sure you already know, the Google Voice app is almost worthless on BB. I ended up using my regular Verizon number, adding GV's voicemail and not using any other features of it. It's such a pain to make calls, even with the app (can you imagine using it before the app came out??) that I haven't told anyone my GV number.
