I've had mine since day one. Scratches on the camera bezel and a little nick on the bottom corner from a drop. You can't really see it but you can feel it.
I guess that's what I get for letting it go naked!
The white is holding up nicely for me. Been through oily hands, highlighter marks, pen marks, dust, lint etc But it easily wipes away. Like people mentioned above, the metal part does scratch, but I always use a gel case whenever I plan on placing it on hard surfaces or being a little tough with it, otherwise, it's usually naked at home. I love the feel and grip of it and it's still as glossy and white as ever.
White holds up well, camera bezel does have a few small scratches. I keep it in a pocket all day, and in the evening it does get tossed around a lot picking it up and putting it down pretty regularly onto hard surfaces. Holds up quite well, now that I think about it .
