(1) How big is your main HomeTheater TV?
(2) What kind is it - DLP, CRT, etc....
(3) Are you running HDTV content?
(4) Any notable impressions/cautionary tales about big screen that the rest of us should know about?

(1) 45" Panasonic PT45LC12
(2) LCD
(3) HD OTA via SIRT-151 - AWESOME PICTURE!!!
(4) LCD is still too new. I don't know if it will ever be as good as DLP can be. But for HD watching, it rocks. We don't watch much TV, but now it's pretty much HD or nothing!
