It's not a front-facing camera, but Apple has added something to the iPad since announcing it: A button on the side that locks the screen orientation. Update: Okay, not new, we just figured it was the silent switch in January.
That's right, you can lie on your side and hold the iPad in any awkward position you want—there is no correct way of holding it, after all, according to Jony Ive—and the screen won't seizure back and forth between portrait and landscape orientation. I really hope they add this to the next iPhone too. [Apple via Loop Insight]
