re: Why Apple Must Enable FaceTime On LTE
I'm not so sure that the 700kbps estimate is accurate. Lighting has such a huge impact on low res video such as the iPads vga camera that it could realistically cost a little more than 1mbps.
With that said, I actually don't know anyone who uses Facetime. In my personal and professional circles, it's really served as little more than an idle curiosity. But then, we're also not kids. I'm sure the teenagers would use an untethered FaceTime as much as they use any other form of communication.
Can you imagine having to get dressed for a phone call simply because your phone call is expected to have video? Video calling sounds like a nightmare to me.
