I've had a BB 8830 with Verizon for a few years now. Since the Droids first hit the market. I have been watching to see where to jump on. So I chose the Droid X for the large screen and better battery life than a few others.
So far I am very happy with my choice. I will need to learn quite a bit about this stuff.
It's nice being able to add another app and not have to remove one to make room, as it was on my BB.
