Summary: I've had the TV for a year now and the screen has not lost any brightness and the sound quality has remained the same. I was hesitant to put the TV in a bright sunlit room, but contrary to the general knock on plasma TVs in bright rooms, I have not found the issue of reflections off the screen to be an issue. The few times a reflection might be visible, the swivel base allows you to tilt the tv until the reflection is no longer in play. great, great product.
Summary: With all the pros and cons of this and other HDTV's the only way our family could make a reasonable decision was to actually go to some of the big box electronics stores in our area, and see them in action. Not that 1080p and other technical specifications are meaningless. Just that, there are Plasma TV's. There are LCD TV's. There are LED TV's. And each manufacturer will be selling their particular technology as "the best".
Summary: Have now had this set for well over a year. Still glad we bought it. Takes up far less of the room than did our old rear projection DLP (also a 50") and we put a nice new piece of furniture under it. While we had originally intended to buy an LCD (or maybe even 3D) TV, this Plasma set just wowed us with beautifully saturated colors when compared to about 20 other sets (most were LCD) all playing the same material (and while it draws a bit more power, it's not a hog).
Summary: I was a little concerned to buy this TV after reading the reviews here. I bought mine locally here in Michigan from ABC Warehouse after it was recommeded by the manager I know there. This TV has a great picture and is easy to use and set up. I saw there was a firmware update for it to correct the 24p judder that you get with some Blu-ray movies. I downloaded it on a flash drive and plugged the flash drive into the TV. It recognized it and updated it with no problems.
