I noticed that the screen on the screen on the new Air feels "springy" and "cheap". The Ipad 4 and prior generation screens felt "solid". When you tap on the new Air screen it feels like it is hollow (springy effect) below where as the prior generation ipads when you tap on the screen if feels solid (solid glass like). Obviously the screen is new and lighter, but damn I am not happy with it. Also does not feel as "smooth" when gliding finger over it. Like the reduced size, but would rather have the same glass screen as the prior Ipad generations. Should have kept my Ipad4.
