I haven't used a screen protector or case on my white iPhone 5, and I don't have any scratches, scuffs, marks, whatever. It's pretty much perfect. I do have finger prints all over it though.
I have never once dropped any of my previous iOS devices, but I did have cases on some of them for months at a time. After a while I get sick of the cases and screen protectors and take everything off. I hate the look of an iPhone in a giant bulky ass case. So I say **** IT and go completely naked.

I hope you completely shatter the screen and can't get it replaced.![]()
I hope you shatter your screen, cut your finger and then can't get it replaced
