In a freak'n book. The Bookbook. I don't know about you lot, but hardcovers that look that used automatically bring me to negative place in my life. One that involves libraries and research. And I'm far to old for that (not to mention that my brain is fried).
The only drawback here, is that it looks like it's only made for a mac book air. And mac book air are about as useful as a piece of loose leaf. Which...maybe appropriate in this case.
