I'm not exactly disagreeing with you, but we don't know yet how well LED PJ's hold up, they have just come out the last year or 2. Maybe they will turn out to be the best, but they are still not very bright and 1080p in LED is not out yet, but should be soon, and then we will have to wait a few years to see if they really last. I agree in principle but it's theory. Now from the stuff that has been out the last 5-10 years, what has held up the BEST is interesting question, something maintenance free , except for changing the bulbs, right?. I guess we have to look to forum rooms , not sure there is a graph on it, maybe there is, I don't know.
