I'd like to keep the Air as sleek and light as possible, and would like to go with the same setup I used on my 1st Gen Ipad. That is, A nice transport sleeve "waterfield", And then just a thin hard plastic back protector when it's removed from the sleeve. I can reuse my sleeve, but need a new back shell. Why can't I find the one I want. I found it in about 5 minutes for my Gen 1. What a want is what I had before. It was a very inexpensive thin plastic rear snap on shell. But, this shell has a grippy feel to the outside. It both feels, and looks like black rubber. It also has a nice cirle cutout for the logo. It adds almost no additional size to the Ipad, but does offer some protection. Where can I find one for the Air?
