i went on VZW 600p>650p>700p>700WX and now 8330 still on VZW. and i wont ever go back. i do miss a few things about the treo but overall and by far the 8330 is > the treo's.
ya wont be using a puck on the BB but the VZ navigator rocks. been using it daily for 2 weeks now and love it.
I have not loaded one single app for anything yet as there is no need to. it flat out works and works well.
