On the phosphor trails: I only have a Gamecube, but I hooked it up last night briefly after reading the posts, and played around in Metroid Prime. The color in the level I was on was mostly "earth tones", but I found an area with some white lights, and did see a little fringing or phosphor trails on those, but nothing to the extent the picture is showing. The rest of the time I didn't notice it. I only messed around with it for about 10 minutes, and the main thing I learned was that the Gamecube looks horrible on an HD screen! Anyway, until I can hookup a PS3, I don't think I'll really have a good idea if this is a problem or not. I'm hoping that as the pixels age, green trails will be less noticeable.
We were rebels and watched the NCAA tourney last night for four hours. I have the settings on Standard right now for the break-in, but didn't notice any ill effects from the scoreboard or scrolls. The only HD signal we have right now is from rabbit ears, but it looked very good. I also popped in some standard def DVD's (480p) to watch a few scenes, and was very impressed by how the newer DVD's looked. SW:EPIII looked fantastic. Pitch Black didn't look so good (very grainy and lots of artifacts).
I doubt I'll post a "review" because I've never owned and HD set before and don't have much to compare to and don't want to hear comments to that effect, but I will give my impressions from time to time and answer questions if there are any. As soon as I get a stand for the set, I'll post some pics. I will say that the set looks really good as far as styling goes, and the "chin" is a non-factor.
