white Macbook interior scuffs

Is it just me, or do the grayish interiors (i.e. wrist areas) of the white Macbooks scuff way easier than iBooks used to? The scuffs I am talking about are the ones that are usually invisible but can be seen as white marks when viewed in proper light. The same thing used to happen to my iBook, but I think my 4 day old Macbook already has more of these scuffs than my 2 year old iBook. Contact with the top (LCD edges) seems to leave a pretty big scuff across the wrist area near the edge, and my fingernail has left a bunch of little scuff marks on the trackpad button at the spot where I usually click.

Has anyone else noticed this? Presumably I have the updated plastic in mine, since it is a week 32 machine. Does anyone know a way to get these off?

The marks don't particularly bother me since you can only see them from an angle in direct light, I just want to make sure there isn't something wrong with the plastic on mine, since I was not used to getting them this easily with my iBook.
