I'm getting a white one (though the fingerprints isn't the main reason - my wife's iPod is black, and mine is white, so I thought I'd stick to that).
Those are my exact reasons for color choices.
The black plastic looks similar to that used on the Playstation Portable, which has a serious fingerprint problem, but other than that is very sturdy. I almost wish for a textured plastic instead of gloss. Necessary evil, I guess, if I have to have that many antennas in a device.
