Is a bose soundlink 3 better than the bose sounddock series 2?

I currently have a Bose Sounddock series 2 ipod/iphone dock. I'm thinking about getting a Bose Soundlink 3 bluetooth dock.
Does anybody out there know if its worth upgrading? Is the Soundlink better than the Sounddock? Better sound. Equally as loud?
thanks,

I think the Bose Soundlink Mini trumps the 3 and the 2 for what I need it for. Think clearly how you like to hear your music, what room, where would it set, how loud will you play it and how big the room. Keep these things in mind. For me the mini works fine in the small intimate spaces in the bed room. In that environment it has proven competent and musical. I have not heard either the 3 or 2 best the mini making them a better buy. The mini seems to be Bose best work.
