Like many of you, I pre-ordered my Touch at the Apple Store but I decided to get it engraved (a first for my Ipods). However, because you can't return an engraved product, all of this chatter of bad screens has me a little worried. If Apple deems that "nothing is wrong" with the screens, then I don't even have the option of exchanging it with another Touch. What are your thoughts on canceling the engraving for a stock Touch and something that can be returned/exchanged in the event that it needs to be? Thanks!
