got it yesterday and am still playing with it. 2 initial things that irked me:
1) if you looked very closely at the blacks (like put your face next to the screen), you can see some white/gray pixels blended with the black. i'm guessing this is normal but i'm curious if this is part of the floating blacks that other people are talking about. this is my first flat screen so it's hard to have a reference - my other tv is a 26" hdtv crt, and it absolutely has no white noise in the blacks.
2) if you again put your head close to the tv, you can hear a faint buzz sound. this disappointed me because i read that some people hear it and some people don't. my tv was a june 2010 build, and i was hoping my set was one of those lucky ones that didn't have that problem. to be fair, it's not really noticeable at all from about 2-3 feet out, and we sit at least 8 feet out so it shouldn't be a problem.
other than that, we've been watching blu-ray on the ps3 and the tv is really stunning. it's amazing how big 50" is going from a 26". it's almost laughable how much more detail you notice in the blu-ray movies and concerts that we've been watching. (dark knight, ninja assassin, the beyonce experience)..
finally, don't use the standard calibration that comes on when you turn on the tv. i realized that contrast is set to 100 by default! i switched to thx mode and turned the contrast down to 50 from 60.
overally, i'm satisfied with this set. it has killer features for the price.
