The problem with all CRT based technologies is that the phosphor coating on the CRT degrades over time. Burn-in is the speeding up of this process. This means that plasma, tube, and most RPTVs are all similar in this. If you could find the exact same tube TV that you bought 10 years ago brand new on the shelf today, you would see the same problem.

FWIW, other technologies have other time-degrading issues. All digital front projectores have a bulb that, not only has a limited lifespan, but also the color degrades with use before it dies. These also have issues with the lamp affecting other pieces of the PJ, things like yellowing the lens.

What I'm saying is, don't be scared off from plasma just because the set will eventually die. I haven't see a TV/monitor with a 100 year life span advertised yet. Don is right, price is the only thing that puts me off plasmas. Well, the size is also limited. Not small enough or big enough for all my needs. Good for the living room, I guess.
