I just got the black one about a month ago. Can't really speak on the durability of the paint. I was more concerned with the glass covering the camera lens. There is no lip around it like on my previous phone and I'm afraid of getting scratches on that. So I put it in a case, which will also protect the rest of the body. Although it does hide the sleek design of the phone, I'd rather have the extra protection.
As for rooting, it's a breeze. Unlock the bootloader, flash custom recovery, install SU binary, done.
