I have an iPod that I take with me sometimes when I want to listen to an audiobook or audiodrama. (I get Stargate audio dramas on cd, they're about an hour long. So, it's kind of like listening to an episode of the tv show...they usually have one of the main characters from the tv show doing most of the drama, with one supporting actor, not always one of the main characters from the show)

I just cant read my Kindle and listen to an audiobook at the same time.

When I listen to music, lately it's been classical music, or one of the movie scores that I've got. (like the scores from Dances with Wolves, and Somewhere in Time...think both were written by the same composer) I have a bunch of movie scores on my iPod, and I'm not afraid that I'll break out into song while listening to them.

Lately, I've preferred to read my Kindle while on the treadmill. The Kindle makes it so easy to read and walk...something that I cant do when I'm not on a treadmill. (but then, I can barely walk and chew gum at the same time...gum is gross actually)
