Here's my experience with some of the issues that seem to inspire the most questions around here. I'll post more details on all of these things later, as relevant, when I post about picture quality and settings.
Buzz. Yes, Virginia, plasma TV's do buzz. But mine doesn't buzz that much. I could definitely hear it every morning when I powered up over the last week+ to start up the break-in disc. And it can be faintly heard in my seating position, about nine feet away dead onbut only if there is no background noise. As a matter of full disclosure, I do ensure the set is in standby when I listen to classical musicas opposed to keeping it on to navigate my receiver's GUI as I did with my old set. But so far the buzz hasn't been a distraction at all while watching TV or movies. YMMV on this due to your ears, room acoustics, seating position, the position of Sirius in the house of Aquarius, and perhaps your set.
Pixels. Still no dead pixels! Hooray! In addition to the few stuck ones that I initially reported that went away almost instantly, I have occasionally noted a pixel or two get stuckbut only when I'm very close to the screen, and it almost always goes away quickly.
Glare. Surprisingly okay. I was bracing for this to be an issue. But the coating does a pretty good job. Last night, I was watching baseball, and my wife and I each had our end table lamps oneach about nine feet away from the screen. There was a small amount of glare on the screen, if you looked for it. But I'll tell you what is reflectivethe bezel. Because of our symmetrical set up, about half of the reflection of each lamp fell on the screen and about half on the bezel. The reflection on the screen was dim and acceptable. But the reflection on the bezel was something else! In fact, the bezel is so reflective, that the inside edges can reflect the image on the screen! This doesn't bother me (it's even somewhat cool), but it is noticeable.
Color. This one really terrified me. The possibility of having colors that were off somehow almost scared me into spending the extra $ for the Elite. But I'm glad I resisted. I watch moves in movie and broadcast TV (read: sports) in optimal. More on this later. But in neither mode did I find the colors to be a problem. I have not spent significant time around reference-quality material, so some might accuse me of being so ignorant that my opinion doesn't matter. But I do like watching TV and movies, and I am definitely a picky person in general. With movies, I can't claim that I'm seeing what the director intendedbut it certainly looked good to me. Really good, even with scenes with which I am very familiar. With TV, I cheated a little before my break-in period was over to watch parts of game six of the NBA finals and a few Red Sox home games. I didn't have any complaints about the Celtics' uniforms or the color of the Green Monster. And I am familiar with how both should look. If I shut my eyes and did some mental-gymnastics A/B testing, I could convince myself that there was a little bit of a difference. But it wasn't worth the effort. Yesterday, I watched all or part of three baseball games in HD. Now, I can't swear to you that the grass was the same shade of green as it was in real life. But all of the fields' were within the possible range of green for real grass. I'm not going to deny that the color over-saturation exists; I don't claim to be an expert in such things and I believe those who say that it's present. And, again paying real close attention, I can sort of see that there may be a little more pop to bright greens. But it doesn't bother me and I only notice it if I think about it. And look at it this way XX20 ownersthe grass will always be greener on our side of the fence.

The lack of settings generally. It is definitely weird to have fewer settings to play with than on almost any other piece of equipment I own. Really weird. But once I got over that, it was a non-issue. IMO, Pioneer did a really great job implementing a set of modes that can be almost everything to almost all people. Remember, most people out there think that gamma is something that only causes issues for Bruce Banner.
