I agree that facetime will become a "Watch what my phone can do" feature that is rarely used, but honestly, I wanted a front facing cam for taking self photos without having to turn the camera around everytime to see if I got myself in the shot.
Although, I do think down the road, the facetime feature could be opened up to other apps and perhaps they could arrange something with AT&T to make it work over 3g.
