My wife is a teacher and her principal recently bought every class an iPad 2, which has proven to be a great teaching aide. However, he is apparently planning on advising all the parents to also purchase iPad 2s for their children. Knowing how quickly iDevices come out, and are subsequently discontinued, my wife is worried that suggesting iPad 2s instead of the iPad 4 (or even the 5 if it comes out soon) will prove to be bad advise which could come back to bite them. So I guess the question is, has anyone heard any rumblings on when the iPad 2 might get discontinued? Or even any educated guesses? Thanks in advance.
