I browsed for iPod-compatible titles and found a few; however, I received an "Unexpected Error" regarding formats when trying to add the titles to my cart. I went back to browsing only MP3 titles and found one that seemed interesting. This time it worked like a charm! I was able to download sections of the book and it played flawlessly.
I would give this app four out of five stars. It isn't a huge deal, but it would be nice if you could search for and download titles within the application similar to Stanza and other apps. Also, I know the app is for eAudiobooks only, but Overdrive also includes EPUB, PDF, and other formats and it would be nice if those formats were supported too. All in all, this is a wonderful app!
