Just wanted to throw this in here. I've had my 50ES set up since Thursday and I couldn't be more happy. I'm coming from a JVC RS40. Right off the bat, the picture is SO, SO much brighter than the 40. I honestly had no idea it would be this big of a difference, but it really is. It's literally night and day (excuse the pun). Second thing that caught my eye was that 3D is absolutely amazing on this thing. I actually don't mind using MotionFlow on Low on animated 3D movies, which is something I was usually very against on other TV models. Ghosting compared to the RS40 is again night and day. 3D on the RS40 is almost unwatchable. I'm using the inexpensive Xpand 103's with the glasses brightness setting at 3. There is a very, VERY limited amount of ghosting in some very difficult parts of movies, but it's only there if you're looking for it. To the untrained eye, I handed the glasses to my wife (who is usually completely against 3D, understandably since the RS40 was so bad at it), and she instantly said that it was 100% better, brighter, smoother, and most importantly, not headache-inducing. Lastly, game mode. On the RS40, fast paced games like Mario, rhythm games or FPS's that require quick reactions were unplayable. With the Sony, the refresh rate is as quick as my Samsung Plasma I have upstairs. I didn't measure anything to get exact numbers, but Game Mode on my Samsung is about 20ms and I can safely say that the 50ES is very close to that. That's a HUGE improvement from the 80-90ms that the JVC offered.
Those are the three features that stood out to me the most. Everything else I mentioned (black levels, color, sharpness) matched the RS40's performance. I can't point a single thing out that the JVC did better. Again, I'm no professional, but I do work with a lot of video (I'm a motion graphics designer) so I do know what to look for. So, so happy with this purchase from AVS.
