I have dropped my unprotected phone twice--once from table screen first onto a metal heating vent and once from knee level onto tile. No breaks, but I do have several fine scratches at a 45 degree angle, so they are probably from transport in my briefcase against another solid item. Fortunately, the scratches are not seen when the screen is on--only when dark and held up to a reflective light. I'm not going to get a screen protector yet, but I will start being a bit more careful.
