I don't use any cases or screen protectors either. Other than the hip holster I use to carry it, strictly naked. I can give testament to the screen though. One evening, about a month after I got my DI, I was getting out of my car and *ouch* dropped my phone to the ground. It gets worse. It fell on my foot as I stepped and shot across the garage floor about 10 feet to the wall, screen down. I was mad and figured I'd ruined the thing, but for that kind of accident I was very surprised. Now, in the sunlight, I can see a few light scratches in the screen, but it can only be seen in the sun, or directly under a light bulb at night. And since I don't use the screen in direct sun or standing under a lamp, they don't ever show up when I'm using it. Typed this just now using my phone. It's not bulletproof, but the screen really is high quality and resists scratches extremely well. While I wish I'd had a screen protector for that moment, in the long run it doesn't bother me at all. Plus, if it gets worse, got the insurance.
