Rising they all have it... Eventually it in the design as a feature. You may not notice since it gradual. As for floating it depends on lighting environment , if you watch alot in darkness your chances if seeing it are better.
Since I never said one word about his integrity, I do not see any reason for you to feel that you must defend it. In fact you just confirmed my exact point, that Phil engaged in premature gushing, just by looking at a panel on display at CES. He was the one who kept trying to get the Panny rep to admit that it was really a Kuro display they were looking at. He said to the Panny rep: "That's A Kuro we are looking at, isn't it". The Panny rep. played coy, and would not say, one way or the other, because of course he did not want to kill the impression that was being conveyed, that it probably was. Good publicity , even if it is not factual, is something a rep. never wishes to dampen.
I hope Phil learned from that experience, and cools his jets this year, until he has put an actual unit through it's paces.
