I am just about to buy the touch (FINALLY), and I just want to know if there's anyone that does NOT have some sort of protective cover or case or sleeve for theirs. I really would rather not have one, because frankly, putting a case on it makes it look ugly, and not how it's designed to be. I want it to be small, sleek and shiny. Anyways, would it be a bad idea not to have one? I know the screen isn't easily scratched, but I hear the back is. Does that really matter so much? If I just keep it in my pocket, or set it down on a table occasionally will it get noticeably scratched? If I NEED a cover, what is the most minimalist, but also functional and not annoying product? thanks.
