New meaning to the term ‘audio book’

I’m surprised that iPod case manufacturers had not cashed-in on this idea sooner; iPod cases made from books [via Popgadget]. I guess anyone with a little time, an extra book, and an x-acto knife could whip one of these up. I would feel a lot more secure walking around holding a textured book rather than a shiny [slippery] iPod in hand.
