I want a protective skin (I think) that also looks classy for my MBA 13. Any recommendations? I was thinking of something like the Cretouch. I can't figure out if this skin covers just the front or the back too? Anybody have it? Sena leather case - it is quite pricey at $150 but it could be worth it if it is VERY nice. Anybody have it? Other ideas? I need a skin that stays on 100% of the time. It needs to go with me and be used in my pickup so it cannot be fragile. Thanks!
