I may be wrong but I would not use a camera on my iPad much, especially front facing, I rarely skype to begin with, only with my brothers family on the east coast about once a month, of course that's me. Plus I have yet to even use FaceTime, maybe it's my generation mid 30's, though the business world may like it, and of course the big time FaceTime fans.
Just would feel odd using the iPad as a camera, I'm sure I would use it a bit. When I first got my iPad I tried to feel how I it would feel as a camera and again just odd. USB or SD would get some use, of course with an iPhone for I'm use to synching.
As long as they they make the iPads better all around then great, I love mine, and don't want anything to make them go downhill. Though it will be a long time till I upgrade, time for other apple products I need more.
