I am a bolter looking forward to the note 2. Despite the bad wrap of the Thunderbolt, it has been a good phone for me. That said, the note 2 is a beast and I can't wait to get it.
Former bb user here...surprisingly I thought I was going to hate the on screen keyboard but I find my self really liking it. Especially in landscape mode, I don't think you will have too much trouble adjusting.
