Is use of the front-facing camera going to be limited to using Apple's FaceTime? I personally find the front-facing camera on the iPhone 4 useless since many of my friends don't have an iPhone 4.
If it was possible to use something like Skype video on the iPad using the front-facing camera that would be very cool.
The newest version of Skype on iPhone does video calls with the camera. So I don't see why they won't support it on the iPad also.
