I upgraded from a 64GB iPad 2 to a 128GB iPad Air. I love the Retina Display and the speed boost. iOS 7 is glitchy, and I think that's what makes the iPad Air seem slow because of the way the OS stutters sometimes. The only complaint I have Is the screen tint issue. Otherwise, I love my iPad air. I think the weight is awesome and the performance is super fast. I play a game a called Infinite Flight, which runs beautifully on the iPad. What are your thoughts on the iPad Air?
