For everyone here who just uses a backpack and a sleeve, do you ever put a skin on your laptop? If you do what brand have you had the most luck with? I use to use an Incase shell on my old 4 year Macbook Pro and when I took the case off, it still looked brand new. On the Retina I thought about just using a clear skin, at least for the bottom (that is where the most wear and tear was for my old laptop case) and then use a sleeve/backpack combo instead of a hard shell/backpack combo before. At the moment my laptop is in an old sleeve I had for my bulky 15" MacBook Pro and I am afraid to take it anywhere because it moves around so much in there :/ I'm just trying to weight my options before school starts again this fall. I know this isn't a review, but after I make my purchase on whatever I get, I'll make sure to post back.
