Perhaps not everyone fawns over their phone and puts in in control of their habits.
My phones have never had a case. I don't care if the back scratches as long as I have none on the screen. I keep coins, zippos and keys in my pocket with them and just by turning the phone such that the glass faces my body and the keys are on the outside there's never been any scratch on any of my phones.
Anyway, whatever, think whatever you feel like thinking. I just find it strangely suspicious that Apple, out all companies, who values design so much and was so happy about the awesomeness of their new antenna design and the chrome rim around the phone would go ahead and launch a rubber band which hides said design, and does so on day 0 just after announcing the phone.
