What is the "correct" name for the new iPad? Is it also called the 3rd Generation?
Yes, it is somewhat confusing isn't it. Almost like, the iPad is having an identity crisis. I believe the official Apple line would be that it is the "New iPad" but I see it referred to the 3rd generation just as frequently as the new iPad.
Siri will be available for the "new iPad/3rd Gen when iOS 6 is released this fall.
