Though nothing quite says “I have the thinnest computer in the world” like a manila envelope, the tan paper sleeve doesn’t add much in terms of protection… or ostentatiousness. Perhaps it’s time to upgrade to this leather version, which will keep your Macbook Air snug and (supposedly) safe while still giving a knowing wink to a promotional gimmick that got old ages ago. Priced at $38.50 and available imported from Japan from Bird Electron. [UberReview]
