I'm seriously considering it. I've had my 3GS for almost a year with the screen left naked and just an incase slider to protect the back. I just make sure I don't put the phone in a pocket with any loose change, keys, etc (put that in the other pocket) and it's been good to go. Anyone else seriously thinking about going completely case-less/screen protector-less with their iPhone 4? Any reason not to, considering the glass is supposed to be even more scratch resistant than the 3GS?
