Does the iPad Air have stereo speakers, or is the second grille just unused or one of the microphones?
Does the iPad Air have stereo speakers, or is the second grille just unused or one of the microphones? If so, that means there is a mic within a grille and a noise cancelling mic up top? (Or rather the mics are the same and the difference in recorded input is adjusted for noise cancellation..)
Just looks a little odd on the spec page and you see 'built in speaker' pointing to one grille with nothing labelling the other grille.
iPad, iOS 6
