Why FaceTime Matters

The Europeans are pointing out that they've had video calls for years and never use the feature.

My question is this: can you switch in-call?

My guess is that the killer feature for Apple's new FaceTime feature is the off switch.

I'm talking to a family member and I mention that my dog has wandered into the room. "Here, let me show her." The key is this: I would never make a video call to a family member except as an experiment, but to be able to fire it up and show something interesting? That's way cool.
