If you want to make sure all your future business partners know that you bleed Apple, this MacBook is the only one to buy. Cause it'd be totally gauche to put "Apple Fanboy" on your business card itself.
In addition to having an adorable little keyboard, a dock, and a menu bar, the screen is replaced by a compact mirror, so you can tousle your hair, adjust your makeup, or take a moment to consider if your love of this particular computing company has gotten a little out of hand.
There are miniature versions of the MacBook, the MacBook Pro, and the MacBook Air (just when you thought it couldn't get any skinnier). The card holders run around $30, though you might need to enlist a Japanese friend to help you navigate the product page and make the purchase. [Apple Mirror via Cult of Mac]
