Mac users say whaaaaa?!!! TwelveSouth is debuting their BookBook: a leather case for your 13 inch or 15 inch macbook. Dec’d out like a vintage library book, each case is exclusively designed so that no two are alike. Consisting of a rigid hardback cover, each BookBook has a padded interior and a zip closure (complete with worn leather zipper pulls). BookBook comes in vintage red or black and ships free for the total cost of $79.99.
