I agree. That looks bad. Might as well have bought a refurb BlackBook. I say a skin does essentially the same thing for resale and lets you appreciate the look. If it's not a fashion accessory, why keep it so protected. The other thing about all the Speck hardcases that is rather unfortunate is that they allow dirt to get in between the case and the MacBook which will then scratch the MacBook as it moves around. They are great for giving extra outside protection, but not for keeping it scratch free. That is where the skin really helps. The clear Speck case looks better in my opinion but still would avoid it for the same reason.
Fashion accessories are meant to be shown in all their splendor. I've never seen another woman carry around her new, exclusive "it" purse in the dust bag it comes in at purchase. Or plastic wrap, for that matter. Shrugs.
