+1 on the no difference, but I wanted to add that another advantage of the ipod is the ability to use playlists. Alternatively if you're using a thumbdrive, you can just organize files into one folder to effectively create a "playlist", but if you're using your ipod all the time outside the car and want to listen to your playlists, you may want to consider just hooking that up into the car.
