I, on the other hand, still prefer CRT, either it be tube or projection. I just don't think you can beat the price to image quality ratio: look at the Circuit City sale on the Sony 34 inch, that TV has an amazing picture quality [better than many of their much more expensive sets] but people avoid it due to the size issue. I have a Panasonic 30 inch which makes looking at other TV's near impossible. Tubes have infinite viewing angles, incredible contrast levels, the best color, and they last 20 plus years if you take care of them! Professional monitors are STILL CRT's, just so you know.
I also like CRT projection TV's, mostly because of how good they can look if properly calibrated, and just how insane the size to cost ratio is: there's no other TV where you can buy a 60 inch set for $1000. Not only that, properly set up and in the proper room and they look beyond amazing. If you're looking to buy, Circuit City sells these so cheap it's sad. I saw a 60 inch Hitachi for $899 new, and on the other side of the spectrum, a piece of shit RCA for $300 new, it's insane. What is true is that the black levels on CRT are still the highest, whether it's tube or rear projection, it's pretty much undisputed. The only disadvantage is the viewing angle [but a dark room quickly fixes that] and the size [but then again, that's only if you're an interior decorator or you live in a 1 room apartment in tokyo] A CRT shines if you get it calibrated.
As for plasma VS LCD: I prefer plasma. High contrast ratio, fastest response time, best color seperation, I think plasma is much better looking than LCD in most cases. The only issue is "burn in" but that's why my computer monitor is an LCD and why a plasma is for movies and games only, as long as stuff is moving on the screen constantly, there's no such thing as burn in: at least on new sets. Old ones? Yeah, maybe, the new ones [made by major brands such as Pioneer, Panasonic, and LG] don't suffer these problems at all. If you don't believe me, play an hour of DDR or Street Fighter and look for the IR, unless you left it paused, it's no where to be found.
And then DLP? I'll be honest, I know nothing about them mostly because I could careless. I haven't seen one DLP where the image doesn't look blurry, colorless, completely dark, or grainy as hell. Blame store set ups, blame store lighting, blame whatever it is you want, but I've seen tubes, projectors, CRTs, plasmas, LCDs, all looking great and beautiful, but I've never seen an attractive DLP in my life. Yeah, they're getting brighter, yeah, they're almost as small as some plasma/LCD sets now, but besides my issues with image quality: dlp owners have the MOST problems with their TV's, from rainbows, to chromabugs, to contrast issues, to outright defective sets.
