Yep. I used to leave my screen on (auto brightness enabled) with Slacker Radio running on my 40 minute commute to/from work. After about 4 months the display developed noticeable ghost images where all of the white control icons and dividers were. It's really freakin' annoying when you're scrolling through sites with white backgrounds. I expect VZW or Samsung would claim negligence on my part if I attempted a warranty claim.
