I was in the Garden State Plaza Apple Store yesterday and I noticed something peculiar about the iPods. Whenever I touched one I felt some sort of greasy/oily residue on it. It didn't smear or come off onto my finger, and all of the iPods looked absolutely perfect. Does anyone have any idea what they use in retail stores to keep the iPods looking so good? I should have asked one of the geniuses but the store was packed to capacity.
