One of the lesser known sections of the iTunes store is "iTunes U" which is home to a large collection of freely available lectures from some of the best universities in the world. In addition to their being wonderfully lacking in cost, everything is well integrated into iTunes in a way that makes it simple and easy to load a course into one's iPod. I've been particularly enjoying lectures in philosophy that are among many podcasts from Oxford. (Thanks, Oxford!)
