That's why its hyperglazed. That's why they put a thick amount of gloss on all white phones. The Lumia 900 white has a nice and thick gloss over it, as opposed to the non-gloss black and blue ones. Haven't seen any weirdness with the other white phones either. The One X is soft polycarbonate and both the gray and white are inherently dirt prone, regardless of color. If you wear it down enough, it actually gets shinier, and greasy looking. The regular shiny white plastic or glossy white plastic should have no issues at all, and very easily wiped.
