I agree with Latufu... get the one you like. You're the one that's going to use it.
Now.. personally, I'd only get the black. I don't like the look of the white one. Mind you, I've only seen pics of it. Funny though... I don't think i'd get a black iPod... I have a white one. Maybe i'm just use to the "black"berry
The pearl is a nice berry... no mater what color you pick.
