Wikistudying...

A website I read had an article on a site that lets you listen to Wikipedia articles on your iPod. The site is called Pediaphon. You just type in the name of the article and it makes an mp3 file of your topic. Then, when you're walking to class, you can listen to your iPod and get some last-minute studying done.

Just a head's up, the voice that synthesizes the words isn't really the best, (basically, it's like have a professor with a funny accent.)
