Audio Books & Text To Speech & Stuff

I have a total daily car-time commute of 80 minutes, so I run audio of various types.

I've collected a sizable audio book library inclusive of stuff by Issac Asimov, Stephen Hawking, Richard Feynman, etc...such fun!

Recently I've been listening to "The Giants of Philosophy" narrated by Charlton Heston* and I quite like it http://www.knowledgeproducts.net/html/phil1_files/philosophy.cfm

I also have "IVONA Text to Speech" which I consider to be the best of it's ilk, and allows me to convert any text to pretty darn good speech. I use it to hone my lesson plans, and read back material I find too dry to read at home, or don't have the time to read. http://www.ivona.com/en/

Y'all running any interesting audio in the car?
