Have iPad Air with only 16g. Ran into problems with lack of space. Bought an Air 2 with 64g. Transition was painless. I bought the Apple 1 piece case/smart cover for it. While the 2 is 18% thinner than the Air when in the Apple case the whole package is just as thick as the Air with a smart cover and a Belkin Shield back cover. The 2 sits down in the case like it is in a bowl. The Air Smart Cover fits the Air 2 so I will see if Belkin is making a Shield for the 2 and try that combo to get back my 18%.
