I have a 50'' Plasma, pretty heavy gaming/TV usage - and its perfect after 15 months, no sign of burn in at all.
Sometimes I see "echos" of images after a while ("burn in"), but after turning it off/on it just vanishes. No long term effects (yet) at all, its still perfect.
Awesome picture as well, I'll never go LCD from here.
