Learning iPhone development while sitting on your couch

I guess this is just part of the huge e-learning revolution happening in our century.. what I'm referring to is that through ITunesU - a sort of university-centered section of iTunes that delivers podcasts/videocasts - you can learn an incredible amount of stuff from the top-teachers in the world. Free of charge, anywhere, anytime.

I listened to the first episode of CS193: iPhone Application Programming and it's just amazing. Please check out the various other things offered at Stanford, really high quality material!
