iTunesU

I can say I will be using iTunesU as long as it stays alvailiable. The iTunesU introduction presentation on YouTube was very informative and persuasive about the advantages of iTunesU.It's awesome that you can practically go to ivy league school's lecture classes, lab experiements, etc. I'm becoming more and more convinvced to invest in a iPhone to have all of this information and all these incredible tools at my fingertips.
