Creating users that want things perfect is what Apple is all about, so it is no surprise that any small fault is easily noticed by them.

In less than a week the people that have bought the new iPod nanos are already complaining about inconsistancies in the finish.

This does not effect how it functions, nor how it looks to anyone other than the most discerning person. Stop complaining to the general public. Just try to get Apple to get you $25 in iTunes credit or something.
