I, too, have seen the YouTube video of the guy going to town on his Droid with car keys. The droid has a scratch-resistant glass screen just like the iPod and BlackBerry devices. Glass screens are a lot more scratch-resistant than plastic screens, which is what other mobile phones typically have. However, glass screens are NOT scratch-proof. They can be scratched by glass and sand. Case in point, I have a BlackBerry that my job provided me for work-related stuff. I put it in my pocket by itself...there was NOTHING else in the pocket. A little while later I noticed some scratches on the screen from tiny individual particles of sand or dirt that was among the pocket lint. I haven't been to the beach in years. It was only a few grains that I guess wound up there from the wind, who knows.
Then, later while I was out of town, I put the blackberry face-down on a wooden table while it charged overnight (I didn't want the screen to wake me up if it turned on). The next morning I noticed a bunch of scratches on the screen just from having it face down.
So, the droid screen is more resistant to scratches than a plastic screen, but it's not scratch proof. I ordered an invisible shield online (with a coupon code). It arrived yesterday in the mail. I'm going to my local mall where there's an invisible shield kiosk and have them install the shield for $10. The only thing I'm not sure about is the back of the phone. I ordered the full-body shield before i had the droid in-hand, so I didn't know that the phone already has a rubberized feel. I don't know if the invisible shield will stick to the back or if its even necessary. I definitely want to protect the screen and the metal edges, though.
