just got a white 1gb nano. popped it out of the box to check it out. one of my ankle biters wanted to hold it for whatever reason. anyways they must have just finished off a bag of lays xtra greasy chips, because now my new nano has two of the greasiest looking fingerprints on it. this thing looks so delicate, that i'm hesitant to just get a clean cloth to attempt the print removal. what is the thing to use in this situation? i'm ordering one of these http://www.shieldzone.com/item_description/APL6090.html so this shouldn't be a problem again. anyone used this product? it was recommended from a long time mac user. what is the advantage over full shield and the one with the cutout other than the obvious? thanks.
