I recently qualified for a free one-month subscription when I purchased an iSkin for my iPod.

I've downloaded two free books but have not listened to them yet. I plan to do this in the next couple of weeks.

One comment about the Audible.com interface is that it is difficult to navigate. It would be nice if I could do a search and then add my selections from the results to either my wish list or my shopping cart. Currently I have to display the details of each book to add them to my wish list. Then I have to go back a few pages to the search results and display details of the next book. It wastes a lot of time.

Other than that I am happy with their service.

BTW - I use Audible Manager to download the files and then Anapod Explorer to synchronize them to my iPod.
