A few days ago, I read this thread thinking 'boy am I glad this didn't happened to me!', although I do sympathize for those unfortunate enough to have experienced this issue...
...even more so now that it DID happen to me this morning. I was going down a fairly long stretch of road on the way to work, proceeded to press ON and +SET...a minute later, I notice a small speck of light above my +SET button. Pulled into the parking lot a few minutes later, and sure enough, upon closer inspection, a small (but noticeable) spot of paint is missing from the top right edge of my +SET button
