physicians using BB? Help me decide

I have used a Palm for years, with epocrates and 5MCC. Most recently the Centro has been nothing but headaches for the 2 months I've had it, now doesn't synch to my desktop. If the Palm Pre had come out just a bit sooner, would have been eligible for that with the new phone contract, but am not now. I use Outlook for calendar, email and notes.

Is it worth switching to a blackberry, and if so which model and which medical applications?
