You may have been to Harvard and the Sorbonne, but have you ever looked at the handsome educational offerings at iTunesU? Well, it may not be an actual bricks and mortar campus, but this helpful application offers up a healthy sampling of lectures, discussions, and seminars from Duke, MIT, Texas A&M, and a number of equally fine institutions of higher learning. First-time visitors should take a listen to Martin Lewis's "Geography of World Cultures" or some of the lectures culled from Pennsylvania State University. Needless to say, this application is compatible with computers running iTunes.
