Hogwash.
NO PLASMA. Plasma's color fades in a few years...little secret, and why they're cheaper now.
What orifice did you pull that info from, Manedwolf?
When doing my homework for my 42" Hitachi plasma, I learned that plasma fading is no worse than a standard CRT television - without the dead pixel, latency, black level, backlight burnout, or viewing angle problems of LCD.
Of course, once you get past 60,000 hrs on the plasma, you're going to notice picture degradation. At that time, you should really get off the sofa and go outside - that's 6.85 years of non-stop television you just watched, and your posterior should be as big as the sofa. In other terms, the plasma would have to be on for 5 hours a day for 27 years before it needs to be replaced. By then the successor to 1080P will be out, and the race to keep up with the Jones will begin anew.
Plasmas used to have a shorter lifespan - up to about 2 or 3 years ago. Advancement in technology's a wonderful thing, ain't it?
As for kilowatt consumption, they can indeed draw some juice. My local power cooperative did a home energy audit, and showed me how to disable the "instant on" feature of my Hitachi. That made a big difference, and I have to wait all of about 3 seconds for the TV to turn on after you hear the internal relay activate from the remote control signal...
