Did I say plasmas have poor pictures? I was merely pointing out things that I have noticed in current models that a prospective purchaser should consider. Overall, I prefer the picture of plasmas over direct view sets and all RPTVs with 7" CRTs.

The burn-in problem I saw on a Fujitsu 5002 which had been adjusted using a Video Essentials DVD. The stuck pixel on a current model 50" Panasonic, dead pixels on a Dream Vision 50". A friend had a different 50" Dream Vision that died and had to be replaced because of problems with overheating. The generous extended warranty was offered for a 50" Pioneer Elite. I don't know if statistically speaking, plasmas are unreliable, but these are personal observations that did not inspire confidence.

I don't know how you "verified" in every instance that motion artifacts were the problem with the source. In any event, I don't have access to perfect sources, I have to live with what is available, and I see all of these problems. I like the overall color achievable with plasmas, but I see posterization problems in dark scenes. I guess you are lucky if you don't notice them. I agree that the pixel issue is really a matter of what you compare plasmas to -- DLP pictures have a greater percentage of fill so pixel structure is less evident and CRT pixel structure is often less apparent because the image has less resolution.

Whether these problems when balanced against the undeniable virtues of plasmas (great edge to edge detail, perfect geometry, high brightness level, vivid and solid looking images with high quality sources, etc.) make plasmas the best choice is entirely subjective. I suggest that a prospective purchaser take along an "acid test" DVD that exposes plasmas weak spot which is dark scenes with lots of detail. The sci-fi mystery thriller "Dark City" would be a good choice.

As for the non-picture issues, I've notice the heat in a small room when a friend installed a plasma; this was not a problem with the 53" direct view it replaced. Since that 50" plasma drew something like 800 watts, vs. something like 350 for the direct view, the additional power consumption had to be either in the form of additional light output (the plasma may put out a bit more light) or heat.

I apologize for giving the impression that plasmas have poor picture quality. That is not the case. I think they are currently at the very top of the pile, but they are far from perfect. I was merely pointing out the weaknesses I notice; the strengths should be obvious at first glance.
