Stu, I think the 50" LCD part is confusing me a bit. If it cost $2,500, it must not have been a flat-panel LCD monitor? I'll just assume it was an LCD projection. Correct me if I'm wrong, but I'll try to lay some points down. I think that LCOS is a term used to describe LCD projection TVs - basically a projection TV with a higher-quality image due to the LCD factor. The image would be extra-high quality with an added 'LSD' factor (
sarcastic). An LCD panel TV is much different - basically it resembles a smaller plasma flat-panel TV and has an ultra-sharp image. The image quality is higher than a plasma TV, but the only problem is that a 30" flat panel LCD is the same price (roughly) as a 50" plasma. 16:9 is just an aspect ratio, basically it is wide-screen, like a screen at a movie theatre. At home, we've got a high-definition (HDTV) widescreen (16:9 aspect ratio) 60" LCD projection TV, and the picture is amazing. The picture quality on this TV is higher than a non-high-def plasma TV (but it's not as good as a high-def plasma).
