I'm wondering if anyone has used any snap-on hard cases for travel on their 11" Air and if they have any to recommend. We've got a few Macs here, and use a Speck SeeThru for the MacBook Pro, but this will be my first time trying a case for the Air. I'm not interested in sleeves or films. Do they add a noticeable amount of weight to the Air? They do to the Pro - at least the Speck does. So far, I've got: http://www.speckproducts.com/macbook-cases/macbook-air/satin-macbook-air-case-11-black.html http://www.myincipio.com/MacBook-Ai...r-11in-feather-Ultralight-Hard-Shell-Case.asp I'm looking for the lightest one possible (preferably), top quality (no Ebay Asian knockoffs), and I'd like it in either black or satin clear (not the shiny clear). Nothing decorative, no patterns, etc... I've had a hit-or-miss time with Speck's quality. My last case from them arrived scratched. I've read the Incipio is lighter than the Speck, but doesn't allow the Apple logo to shine through. Not a huge deal, but would be nice. I'd love to hear if anyone has any alternatives! Hopefully this can be useful for other people, too. Thanks.
