e-audio books

I can hardly wait to get my hands on these. I love audio books for long drives but it's frustrating when a library doesn't have the one I want in stock. Now I can get what I want whenever I want it. These would also be good to have playing on your computer when you're cleaning (not that I do much of that) or doing crafts or something.

Podcasts

Well this is quite cool although I can see that podcasts would be attractive for people who like to do weird rants - white pride people and those kinds of freaks.
For the library I could see a daily or weekly podcast of the children's staff reading a book to kids or some of the adult staff reading exerpts from their favourite books. Or perhaps visiting authors reading excerpts from their books. I can actually see this as being a bit more useful than a YouTube site.
