Since I got my MacBook Pro, I've kinda been going crazy over protecting the damn thing. I went to the Apple Store and actually thought it would be a decent idea to get a standalone sleeve with a strap for my MBP. Just since I don't always need to keep it in a backpack to just bring it around (current hand-me-down sleeve from old HP has no strap or anything). At the store I saw the Level8 Sleeve and thought it was pretty nice. Has anyone else used others or have any good alternatives in mind? Also, the case kinda has to fit a 15 inch MBP with a Speck See Thru Satin on it
. Thanks!
