The previous class on iTunes was extremely useful to me. I'm a college student and the fact that it was in a lecture format made it easy for me to digest.

Reading a book is one thing, but watching someone give a lecture in little chunks made it really easy.

I wonder how ARC changes the way they teach memory management.

I had the same experience on the book vs lecture question. I first read Kochan's Objective-C book, and then started the Big Nerd Ranch iOS programming book. But I never really grokked core concepts, like MVC, that I easily grasped watching Hegerty's lectures.

I think they may condense it down a little. But learning retain counts is still pretty useful, especially when you have older iOS apps to maintain.
