As far as the burn in on the plasmas, most of the newer model plasmas have a feature that "alternates pixels" every few seconds in order to prevent burn in...I know that Samsung has this feature and it works very well. From my experience with both, plasma has the better picture imho, as well as a wider view angle. As of now it really just depends on the size of the television you want to purchase as the plasma's are only in 42" or larger. I also read earlier that someone said not to buy a plasma if your going to play video games. I'm assuming the reason they said this is because unless your watching a movie/tv/playing a video game in HD, then the picture is not much better (if not worse) than on a standard tube television. This is in part because of the large screen size, and also just because everything is going digital, so they are building these newer plasma TV's for digital. A good example of this would be that a PS2's picture on a plasma is not all that great. But the Xbox 360 (because of the HD capabilities) is amazing. I don't know if LCD's are the same as plasmas in this aspect or not.
To sum up, a plasma screen in HD is simply breathtaking (especially for watching golf
)
