As far as audiobooks/ePub books...
Our local library is participating in a new system with other Missouri libraries. It's called Overdrive Media Console, or something. It's a way to download (on loan, like normally lib. books) audiobooks and digital books. You can do it on pc, mac, iPod, BlackBerry, etc. I'm really excited about trying it out. I actually downloaded all the software I needed last night, on my iPod (the Media Console, Adobe ePub software) and as soon as I finish Between Planets, I plan on downloading the ePub version of Blood, Bones, and Butter: the Inadvertant Training of a Reluctant Chef by Gabriella Hamilton (basically kinda the female version of Anthony Bourdain! LOL).
