It might be the angle of the shot, but what's this green light the ear piece? I'm really hoping for notification light. I hate having to keep turning off/on the screen just to see if I missed a call or have a txt/email/ect.. You'd think Apple would seamlessly double up on the video camera LED as a notification light. But after watching the demo there was a no green light indicating the camera was on during Steve and Jony's facetime. Whacha think?
