"The amount and durability of the resin applied as a protective coating during the Nano manufacturing process is clearly defective in that it is not sufficient to adequately protect the face of the Nano from extreme scratching and ultimately irreparable damage,"
Replacing it may not solve the problem – it might just get scratched again. Then again, if I owned a Nano I'd probably want to buy a carrying case for it anyways. Even a cheap $20 2.5” hard drive adapter is worthy of a carrying case to tuck it in. Many people claim the Nano is just fine, and that it is the fault of the person for not protecting it. In any case, with more than 17 million Nanos out there, people are loving them and still buying them.
