Title pretty much says it. As a result of a mistake Apple made with getting a new laptop to me, they're giving me an iPod Touch. I've never even thought about getting one because it was out of my budget, so I haven't done the amount of product research I normally do. So as far as cases/screen covers/whatever go, which ones do you like and how necessary are they? Could it wait awhile to get them, or does the Touch scratch up pretty easy?
