plasmas dont have the image downsides of LCDs but weigh more, use more power and put out more heat.
I have a panasonic 42" 1080p plasma hooked to one of my computers and I run hulu videos on it all the time. Looks good, but not great.
A 120 hz LCD is probably the way to go for what you are going to use it for though. Pioneer stopped making plasmas and they pretty much made the best....panasonic make great plasmas too but I think plasmas are pretty much done with since OLED is almost here.
Personally color representation is what matters most to me and thats why I picked up a plasma.
