I'm in the same boat! Switched from a 650 to an 8703e on Thursday. I've got Alltel. I'm debating whether to stay with the 8703e or switch to the Moto Q when it comes out in a couple of weeks.

So far, I love the 8703. I thought I was going to switch for sure to the Q, but the 8703 is making the decision tougher than I thought it would be! if there's anyone who has helpful BB vs. Moto Q info, I'm all ears....
