For a long time I had a 15" CRT then one day someone gave me a 19" CRT and i loved the upgrade in size. One day the 19" died so i went back to the 15".
Then last year i was very lucky and got a little spare money out of the blue and splurged some on a samsung 37" HDTV 1080p. I think its awesome, i would not want to go back now. I use it for PC and xbox games between 3-5' away. Picture quality in AH2 is amazing at 1920x1080. But i have to agree with TnDep, there is more sky to miss in, gunnery takes time to relearn lead after using a small screen.
PS: the grid on that picture is a result of a cheap webcam, the TV itself is crystal clear.
