I got my first look at a P42S1 at Sears yesterday. It sat with a LG 50PG30, Sammy 50A550 and 46A850. My first impression was "look at the blue snow", but then for the last 12 years I have been watching a calibrated 32" Toshiba "Cinema Series" CRT. So the whites were too blue on all the sets. But, to those that think plasmas need more brightness the S1 is a step in the right direction. It was brighter than both the LG and550, though not quite as bright as the 850. Blacks in store conditions are not as easy to judge but the 850 appeared to be the darkest followed by the S1,LG and 550 in that order. Of course get off axis and the 850 fell off. Also to me the 850s black seemed to have a slight purplish color to it. About the reported green push on the S1, I didn't see it. I saw a slight red push on skin tones compared to the 550, which I thought had the best colors. I did manage to get the S1 and 550 into their respective cinema and movie modes before I was approached and asked if I needed help. At least that was the words she spoke, but I would swear her tone said "What do you think you are doing to my TVs?" While the S1 did not have the brightest whites nor darkest blacks compared to the 850, it did have more details in both (I know not best conditions for this comparison). One big plus for me that I saw on the S1 was reflections on the screen. I had to look hard to see any on the S1 the other three were very visable, something that will mean alot to me in my livingroom. I am no expert and the conditions were not the best, but for other in the boonies like me that are slow to get new products in their area maybe it can help.
