Have to say that this is one of the best "plasma vs lcd" threads I've seen in a long while, with good examples of pros and cons for both technologies. My personal option, and I don't claim it to be anything but that, is that the drawbacks of plasma TVs for "common people" are quite often overlooked and that many owners of plasma TVs seem to be kind of stuck in the emperor's new clothes tale (only seeing what they want to see).
Don't get me wrong here, there are many really good plasma TVs out there, and the VT50 is probably the best of them, and it is really good, but it isn't perfect. For movie watching in a completely dark room it is probably the best TV, even though both the HX929 and the Sharp Elite can give it a tough fight, but for multipurpose viewing I would be more hesitant to give it the crown. Especially if you don't handle it and take care of it like the new baby in the house.
I am quite certain that if a LCD had, for example the same problem with IR as the VT50, it would be seen as a huge problem by many reviewers, even the same reviewers who wouldn't even mention it in a review of a high end plasma. Just look at how many reviews doesn't even mention it, even though I believe that anyone that has spent more than 30 minutes with a VT50 must have seen it.
Again, these are my personal options, they are not facts, and I respect if anyone thinks differently. I don't claim to have "the answer", just "my answer". All TVs mentioned in this thread are great TVs, all have the strengths and weaknesses. But no one is perfect.
