OT: Anyone ever try audiobooks?

[WarDekar]

In my never-ending quest to be as productive as humanly possible, I thought of this: Listening to audiobooks while I multitable. Currently I'm usually listening to music, watching TV or a movie, and browse/chat. What if instead I listened to audiobooks, I could get so much more accomplished as I never really read anymore. Anyone ever tried this? Is it hard to concentrate on both?
