FaceTime for iPad is probably one of the most missed features by the iPhone/iPod users. It certainly would have been a better experience if the iPad offered a front-facing camera and FaceTime. That because of the user-experience that the 10" screen provides over the the iPhone’s 3.5".
You can now solve this problem with a hack named "Intell". This, of course, is a partial fix because of the hardware limitations of the iPad (no front-facing camera) but the other party will still be able to hear you.
I personally loved the hack because it doesn’t just enable FaceTime on iPad but makes it iPad optimized. Hence the video quality is very good.
