I was a long time BB user, curve>storm>tour>bold. The droid X is my first android phone and I love it, will never use the BB again. For me the X can do anything the BB does and better at doing it, then there is all the stuff the X does that the BB can't.
My cell phone is total consumer I don't need a phone for working, so the stuff that I use it for watching movies, surfing the net, texting (love swype), gmail, maps and driving around navigation totally owns the BB system.
I don't many games but they do blow away any game on the BB system.
A ton of great free apps too.
