My wife and I are discussing the difference between a 42" and a 50" TV - (cost not the primary issue), and we can't decide whether we want gargantuan, obnoxious size, or smaller size and more clarity.

While avoiding a discussion over which is better - DLP, RP-LCD, LCOS (if it ever really arrives), Plasma, etc. - I want to know how big your TVs are.

Apparently we all love great sound. But how many of us are buying $2500 sound systems and watching movies on a $500, 27" TV? (Me....)

So, my questions are -

(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?
