I have had the Audible Account since 2001. Started with my Casio Cassieopia. Have used it to listen to books in my car and while out and about walking, waiting, etc ever since. I have had numerous devices using the PocketPC form and the audible listener. Casio, Ipaq, Palm 700W.
Now, I listen to books thru my Garmin, using a direct plug in to my auxilary jack on my car radio. I dont mind my hour long drive each way to/from work
Truly one of my greatest pleasures.
And my new Sony prs700. Man. Life is good!
