My wife got hers on launch and has it in her purse all the time not a scratch on it. You do not need a screen protector for it if you use it for everyday use. Of course, seeing as the screen is glass, it is extremely resistant to many materials, including steel (keys, knives, etc.) and coins (copper, nickle.) However, some stones and rings (tungsten, diamond) will scratch the glass, so be careful not have it in the same pocket with any rings. It goes without saying to be careful to not drop the phone anywhere, especially on rocks.
