Why did Apple make Facetime an independent app?

I think "FaceTime" is really important for them to brand, and by mixing it with iChat you're taking away from that.<p>In the keynote, Jobs called the iSight camera "FaceTime" camera, even. I think we'll see a shift towards FaceTime in a lot of things.

I'm wondering the same thing, surely it makes sense to provide "IM" support as well.<p>It seems logical to attack BBM and gchat.
