Educational Resources Through iTunes U

iTunes is a common Web 2.0 tool that many of our students use on a daily basis outside of class.  Despite the fact that the iTunes Store does have some distraction material, iTunes can still be a powerful tool for classroom use.
One component of the iTunes Store that is useful is iTunes U. iTunes U was originally created to distribute educational podcasts for higher education. However, iTunes U has been expanded to provide educational podcasts for K-12 education. In addition students can subscribe to teacher created audio/video podcasts and download media to portable devices such as MP3 players and iPods for content "on the go." Should students have access to iTunes Store resources such as podcasts and iTunes U in the classroom?  Let's hear your thoughts!!
