I've had LCD & CRT monitors and LCD & CRT TV's. Both have their pros and cons
LCD pros- slim, light, large sizes available, cheap, perfect focus and geometry. Less strain on the eyes.
LCD cons- dead/lit pixels or sub-pixels, poor black levels, off-axis brightness polarization. Not fantastic colour reproduction.
CRT pro- true black, scaling/resolutions don't suffer from the same problems as LCD. Hides Mpeg compression better (lower quality sources look better) Great colour reproduction.
CRT cons- big, heavy. Focus and geometry/convergence problems. Screenburn is a possibility, although unless you leave it on for days at a time you'll be ok.
For PC, I choose TFT. For Windows, text etc TFT wins by far. I can look at a TFT for hours and not get eye strain, can't do that on a CRT (even with high refresh) For gaming though I think a good CRT would be best.
For movies/home theatre CRT, but most CRT TV's have poor geometry. Ideally CRT front projector. LCD TFT making a compromise, they do look bad with SD sources, a lot better with HD. But they still have LCD's problems (black levels/baclight and pixels) colour reproduction is getting better, but still look a little bland compared to the best CRT's.
If CRT could be decreased to a 6" for 37" screen I would stick to that. But they can't, how else can you get a 50" TVT that isn't CRT RP depth?
