Incredible write-up, what a good job, man! Thanks!
Now I get your preferences about what to play, but I assume you are not generally limited to the playlists - you have a mode where you can just operate the iPod on the iPod and thus access music the way you always do on your iPod - right??
For some of us, this is the only real way to operate your iPod - I have more then 18,000 songs on mine and there is no way a small text display will work for me while driving to select a song.
