@wbeckle, yes. And as jay pointed out, with 4G PB coming, so will many of those features.
So while the device would be pretty limited at first. It would be a slate that would be able to update very easily.
2 different devices... Aghhhh not platforms!
I would definitely use a mini PB as a phone. It would be better if it had a physical keyboard for me, though. I do love the OS
