Great article Jeff...I would add to your list of sources,Audible.Com and I-Tunes.
Both offer books downloaded to your computer. I-Tunes can of course only be played on the computer or the I-Pod. Audibles can be played on almost any device. I.E. MP3,I-Pod,computer etc.
One point in favor of Audible .Com is that once you purchase a book,they retain it in a library that you can download as many times as you like. This is a great advantage if your hard rive dies as mine did. 20 books from Audible were recovered. Books from I-Tunes must be purchased again.
