In an unprecedented move, Stanford University is collaborating with Apple Computer to allow public access a wide range of lectures, speeches, debates and other university content through iTunes. No need to pay the $31,200 tuition. No need to live on campus. No need even to be a student. The nearly 500 tracks that constitute “Stanford on iTunes” are available to anyone willing to spend the few minutes it takes to download them from the Internet.
