So I've been trying to find a good hard case or shell for the new MBA 13" but can't really find one that is well made yet. I bought this one http://www.amazon.com/mCover®-13-3-...2?s=electronics&ie=UTF8&qid=1299536679&sr=1-2 and though it is OKAY overall, it is horrible whenever I completely close and open the screen; it rubs very slightly and makes a noise. I'm not looking for a sleeve, I'm looking for a hard case or shell for the new MBA. Anyone have any suggestions or good experiences? Thnx a ton.
