>The weirdest thing in the Google presentation is that several sections had presenters talking to a different camera than facing the screen. That just felt very strange.

Not sure if that is reassuring or a sign of carelessness or a very well planned stunt.

This is a common technique used in film when someone is reading from a teleprompter. It is meant to draw attention away from the speaker's eyes moving from side to side.

Which makes the Apple presentations all the more impressive. The camera is head-on, but I don't notice anyone's eye's moving as if reading a teleprompter. I think they've memorize it

In Apple's presentations they are almost always far away e.g. several metres from the camera.

If you look at Craig's OSX section where he is closer you can clearly see his eyes slightly move left to right as he is reading from the teleprompter.

They did that last year too, it feels more like a documentary/tv show than a keynote.
