I just found out about iTunes U! It’s part of the iTunes store, but instead of music downloads, it consists of educational lectures, language lessons, films, labs, audiobooks and tours. Over 600 universities, including Yale and MIT are active on iTunes U. You can download to your computer or to your iPod or iPhone. In addition to the 250,000 free resources on the site are resources you can download for a nominal fee, i.e. the typical 99 cents. If you already have iTunes installed, just click on the iTunes U tab.
