I know its 720P HD Video, but how about the megapixels is the iSight camera for the 2012 Macbook Air if taking snapshots? Thanks a bunch.
why do you need to know?
It takes pictures 1080 by 720 in Photobooth (0.8 megapixels). It isn't a higher resolution camera than that-- that's just the maximum, unlike the iPhone's back camera. That is more of a limit in processing power though (which is why it can't take 4k video)
Unless this has been changed since last year, Photo Booth can only take pictures at 640x480.

It can however go up to 1280x720 for videos so I'm guessing it's just a software limitation with Photo Booth, not hardware, possibly because still pictures would look too crappy otherwise. That's what they did with the 5th gen Nano if I remember correctly.
Why do you care?
What kind of response is that? The OP has a valid question.
