Well ... it is a computer with a finish that is designed to look good on the showroom floor, and not a refrigerator with a coating marketed to repel fingerprints, dirt, and kids.
As long as the machine continues to work, it really isn't an Apple problem -- since the warranty likely still disclaims "cosmetic issues."
That Apple does something for people even when they aren't obligated to is something, that Apple is attempting to head off a PR issue instead of winning a class action.
The whole finger print issue makes no sense to me. Reason being is all you have to do is go to the Apple store and you can see all the finger prints on them. If they bother you that much why did you even buy it?
