Considering the limit of onboard and expandable memory on phones nowadays an FM radio is extremely useful if you use your phone for music. Think about it: lots and lots of music that doesn't require playlists or skipping through tracks, or worst of all having to plug it up to your PC to transfer files (and waiting several minutes).
Not to mention news and weather.
Used the radio on my w600 about as much as the music player.
Duhhhhh....
