I got a 60 GB black one. (matches my interior) I think it actually sounds better than my old 3G. I got it because I got tired of only driving around with 18 GB of music, and my old battery wouldn't hold a charge.
On the new one, the battery time is outstanding. But you are right- the menus are slower. But it is the Display which has a hard time catching up to the music.
