no offense but, only a fool would NOT use a screen protector. I get it that many of the newer, younger, smartphone users have probably never owned or used a PDA before and have always had touch screens but, even with today's touch screens, it's always good practice to get a screen protector for the phones. Screen protectors are the first thing I put on every phone/device I own ever since my 1st one back with my iPAQ HP2210. Any time you'll be dragging anything across a screen, it should be against the cheap plastic on the glass instead of the glass itself. Dragging a hang nail or artificial nail across a screen is like cleaning your glasses with sandpaper. Fine enough and you'd never notice the scratches. Do it enough times and you'll eventually see it.
