We have an ipod nano 2gb model, and also the ipod classic 80 gb model. We have loaded audio books on both. The 80 gb works best because it can hold more. We subscribe to audible.com and download our books from them. They download and transfer right into itunes, easy as can be. Our Ipod classic has over 100 books, plus some music, on it and there's still lots of room left. Audible.com has ten of thousands of books including bestsellers, non-fiction, radio shows, and podcasts. I've subscribed for over 5 years I think, and I've never been disappointed.
