Cons:

Review:
I've had this TV for almost 3 months now. I've done a "break-in" with full-screen viewing (100hrs), and with the break-in DVD from the AVS Website (100hrs), and turned brightness/contrast down below 50. I still get image retention; even after watching a movie with black bars (will see 1cm long lines near top and bottom of screen). It goes away after a few minutes of watching full-screen TV, but the fact is that this TV will get Image Retention easily if you are not careful or really abuse it. Video games play great with no lag issues, although I highly recommend running the scrolling feature every 30min for about 10-20minutes to avoid IR, unless hud/logos are transparent (like Halo 3) or not there. Not a big deal to get off your butt and take a short break. Games like Halo 3, Dead Space, Mirror's Edge, etc, can be played for hours with no IR issues.

Other than the IR issue, the Picture on this TV is just phenomenal. Blacks, colors, sharpness, you name it, the picture quality of this TV blows the panties off other current Plasmas (except maybe for Pioneer's, but it is damn close). It's the thinnest plasma I've ever seen. While the stand looks very sexy, you won't regret hanging this on the wall. Was a bit paranoid leaving the LED bandwagon and jumping on Plasma, but I think I made a smart choice. All in all, one of the best pictures I've ever seen on a HDTV.
