I'm still pretty careful with it: I don't put down on hard surfaces without a cloth or something under it, but I still have it completely naked. There are a couple of miniscule marks on the chrome, but no other marks or scratches anywhere, even on the on the back. I let a friend's four year old touch and play with it , but only when I'm holding it. I'm the type who's always pretty careful with my things, but I'm still a little more careful with the iPhone than my other gadgets. So far. It's naked at home or in my pocket, but in an iPod sock if it has to go into my purse. I couldn't find a nice enough case to cover it with, so I gave up and went with what I had at hand, and I'm pretty happy so far. How about you? Has the shine wore off? Are you treating it more casually?
