Bought one the other day and love it.
Have noticed a couple of things.
First, the THX settings are way too washed out on my set. The brightness levels are too high. I am still playing with the numbers, but am using the THX with a Brightness of 37.
XBOX 360 component DVD video is AWESOME. Very crisp, very nice.
NOTE: when using the XBOX 360 component video, the images will show occasional bit-stretching at 1920x1080. This is a function of the XBOX 360--not the TV.
When using the HDMI cable with XBOX 360, the 1920x1080P is perfect. Halo 3, Grid, and Mass Effect have never looked so good. Playing movies is also excellent.
