sorry, i didn't mean the case.. i meant to say the Smart Cove; are they the same?
The old Air Smart Cover works pretty well on the Air 2, but I don't think it's exactly the same as the new cover. My quess is that the hinge on the new cover is probably a little smaller since the Air 1 cover hinge sticks out slightly on the back of the Air 2.
AFAIK, the only smart covers you can buy are the original covers for the Air. There is no actual smart cover for the Air 2.
The only thing different about the Smart Cover are the colors.
