The interface just isn't as nice overall. It gets the job done, but it's not as intuitive or pretty as the iPhone's player.

Also, the vast majority of people have their music in iTunes. The fact that they can't just plug in the device and tell iTunes to sync might be a turnoff

The vast majority?

Seems like it. I'd guess that it's ~90% of mp3 player customers in the US, but maybe I see a biased sample.

anecdote: friends and family have spent at least 20 thousand dollars on music in itunes. The people who even know alternatives exist are only tech people and they don't spend much money on music.
