Having spent a year or so studying Computer Animation and Modelling, it's fairly easy for me to tell that's a rendering. As far as I can tell, Apple generally uses actual photographs of their products in keynote slides, and if nothing else, they don't use weird angles like that. But as a mockup, it's not a bad idea.
Could be a front view. Starts with a (very) wide screen for movies. The camera is a front facing webcam. Nice little Apple logo on screen at the moment! The area above and below are multitouch input areas so you don't have to get fingerprints on the screen.
This is actually a picture of the front. There is no screen, and like the current iPod nano the entire tablet runs on a voice controlled UI. The front facing camera will implement Apple's new emotion sensing interface (frown to turn down volume, smile to turn it up, etc.)
