I just got my 50c450 a few hours ago and I am starting this thread as promised, I'll be updating this first post with any relevant info as it comes up.
The set buzzes, no question about it, I can hear a loud buzz. I'll see what Samsung says about it before I call Amazon for a replacement unit.
Picture Quality is very good, easily on par with my old 54V10 in many areas. The AR filter is noticeably better than what Panasonic uses resulting in deep blacks even in brighter lighting, but it was overcast out so that may change on a sunny day. Line bleeding is present, but I'm not sure how it compares to other plasma brands just yet, I still have a lot of extra testing to do. The good news is that there is almost zero dither noise on this set, resulting in one of the cleanest plasma images that I have seen. Green Phosphor trails is also very hard to spot, about on par with the 2009 Panasonics which were very good and it should get even harder to spot as the set ages.
Overall I am very impressed with this set, especially for the money I paid. (even at MSRP these sets are a steal) If I can get the buzzing fixed then I could easily see this becoming the best bargain set of 2010.
I still need to see how this set looks in a completely dark room, so I can't wait for tonight to see how deep the blacks are.There are black spacers between each horizontal row of pixels

I would sit at least 6' back from the 42" so you cant see the lines.
Here is the video that references the black lines between the rows.

(and the pixels are rectangular like on the 42inch models) After I figured this out I remembered a CES interview where a Samsung Rep said they were doing this on all their sets to improve the blacks in room lighting, they said that any blank spot between pixels would be "painted" black, what they didn't say was that they were going to add blank spots to achieve this.
(my 42px75 Panasonic plasma has no spacers between the pixels, and I would bet money that none of the previous years of Samsung plasma sets had them either)
Normally I can sit 8.5 feet from a 50inch 720p plasma set to get all signs of screen door effect to vanish, but thanks to these black lines, I have to move to 14.5 feet to get them to vanish. I would guess that roughly 1/3 of the screen is made up of these lines, maybe more.
At least this actually does make the blacks look good in room lighting.
I have no idea what I am going to do at this point as my replacment from Amazon has already been sent out, and there is no way that I will be able to put up with these lines.
Here are my latest settings as of December 03, 2010
Movie Mode. (Standard is too dim and Dynamic is useless)
Cell Light = 10
Contrast = 75
Brightness = 55
Sharpness = 0
Color = 44
Black Tone = Off (didn't notice a diff with it on so I left it off)
Dynamic Contrast = Off
Edge Enhancement = Off
Color Temp = Warm 1 (Warm 2 has always been too green to my eyes)
DNF = Off
Screen Burn Protection = 4/4/1 for gaming and TV 2/2/2 for movies
I'll be happy to answer any questions about the set that I can, so ask away.
