I've exchanged 7 iPads. Every single one of them has the yellow tint on the left side of the screen. Some worse than others. Bought at different stores, same issue. QC on these is incredibly poor. At this point, I'll hold on to the one I have and see how the retina minis are when they come out. Maybe the smaller screen size means less to mess up. Biggest lesson from this whole ordeal is to definitely buy at an Apple store or a store with a liberal return policy. Otherwise good luck getting an exchange.
