Well, I picked this up Friday night. Got Wallyworld to price match Costco's $569.95.
I am pleased with this being my first 1080 set. Been watching a 720 Samsung 50" in the living room.
A few things bothering me are even with Cleartype text on Windows 7, I can still see lots of pixelation. I guess it doesn't help that i'm only sitting 2-3 feet away.
There are jaggy's when viewing 3d, but it's really not that bad. Once i'm into the movie and sitting far enough back, I forget about it and don't notice it.
I tried a few sports channels and tried turning on and off the motion features. I don't know if it's artifacting from my cable compression or what, but sports wasn't very impressive. It looked better with everything on high including noise and mpeg though. Had sharness on 5. I did read later on somewhere that any amount of sharpness would produce artifacts and haven't tested again since going back to 0 sharpness.
Overall, great picture and colors watching film and happy with my purchase.
