I've had my new MBA (2.13 GHz w/SSD) for just over two weeks now and love it. The one thing that isn't working for me so far is the inCase neoprene sleeve I bought with the MBA. I find the flap closure awkward, and suspect that in fairly short order it will get stretched out, greatly diminishing the protection it offers the computer. The problem is that every other 13in case I've seen is built for the noticeably thicker MacBooks and MBP's - the Air 'fits' but it rattles around inside in ways I don't find particularly comforting. Can anyone recommend cases or sleeves other than the inCase that are built specifically for the Air (or at least with other ultra-thin notebooks in mind)?
