Pros Cheap and usuable
Cons no problems whatsoever
Summary I don't have a very large music library, but I've had people who do use the ipod dock and they don't have a problem with it. I suppose if you're looking for a very specific song or playlist, then it'll be problematic, but when on the road, you should be fine with going on a certain playlist, artist, album, etc. There's always the next track option if you don't like your songs.
Good sound output, dedicated ipod connection also with an auxiliary audio in, bass isn't bad. Good, usable, and cheap receiver.
