My Incredible DOES have this problem, and it's not as rare as people are making it out to be. I've never set the phone on top of foam in the middle of a thunderstorm on the night of a full moon....
Actually, when I'm sitting on my couch (leather, not fabric), if I sit the phone on the cushion next to me, the touch screen does NOT work properly. I cannot get the phone to respond properly, to the point that I can't get past the Android swipe unlock pattern. I have to pick the phone up off the couch and then it works fine. I thought I was crazy until I saw this thread, but sitting my phone on the couch next to me is a very common occurence. Not that it's anywhere near a deal breaker for me, but it is annoying. I'd say this issue happens to me at least once every 2 days -- and we don't have that many full moons and thunderstorms where I live
