I don't think it's the few scuffs and scratches that get me to buy a case, but instead the unforeseen freak accident drop on pavement that could really damage it. I can see myself dropping this thing once over the course of a couple of years and really putting a good gouge in it that will affect the feel and shape of the phone more than a small scratch, if not ruin it completely. I'm doing what i did with the 4 because of the glass: getting a case for day to day transport, running, going out, etc that snaps on and off easily, incase makes one. Then, when I'm at work or at home for the weekend I take the phone out and use the case as a pad for it so it's not scratching against tables and whatnot. This may rub the finish off of the corners but helps possibly prevent the massive freak accident that I tend to be concerned about.
