it's a bit thicker, but is overall the best player of the three, in my opinion.

It natively supports many formats for video, so you won't have to encode the files to play on the player.

it has FM radio and FM radio recording. and voice recording, which you'd be suprised when it comes in handy.

it's screen is the same size as the iPod, but with about 200K more colors. It also had a search function before the iPod.

One downside is the battery isnt as good as the new ipod, though it was better than the old one.

The gigabeat is the worst out of all of them. My recommendation is look online for reviews. check out for a great, in-depth look at the ZVM.
