So you sprung for the MacBook Air? Then I don't feel weird telling you to spring for a custom MacBook Air sleeve from AB Sutton. You pick a hot shade of leather to sheath your laptop in, and provide AB Sutton with your initials for a monogram, and then looky: No one's going to mistake your MacBook Air for their MacBook Air at the airport or at Peet's.
Available in a too-many-to-count rainbow of color options (seriously, it's like paint-chip nation in there), the cases cost $278-$348 a piece. But what a small price to pay for sexy protection for your sharp, little machine. Consider this your enabling.
