1) Independent of CRT strengths and weaknesses, CRTs will fade from the market, becoming niche players over the next 5 to 10 years. Why? Money. CRTs are a mature technology, and are stable or increasing in price (vacuum, special glass, lead, hi voltages, etc). LCDs and other technologies are still maturing and the price is dropping 20% per year or 2% per month, depending upon who you're reading. Do the math. LCDs and perhaps other technologies, will become the cheaper low end of the market, even before they are cheaper than CRTs, due to power consumption, size, weight and image perceptions. Read some industry articles and see how some companies are scheduling shut downs of CRT plants. Another way of looking at this would be to view SEDs as the "new" CRT, flat and still using the emitter/phosphor approach. So if SEDs make it to market, and are successful, the CRT can be considered to live on.
2) LCoS has long been viewed as a long term winner. Every new technology must be developed, and not every company successfully does it. JVC has been selling their own design and manufacture analog LCoS front projectors for years. They use digital LCoS for consumer RPTVs due to cost, maintainability and volume manufacturability concerns. They buy LCoS silicon substrates from Aurora and put their own "LCD" portion on it and build the rest of the TV (note that car companies buy diesel engines and other subassemblies- why should TV companies be any different?). Do a search and you'll see many threads on LCoS. Sony and JVC are not the only companies pursuing the technology. You'll see postings about how much JVC is expanding manufacturing and sales and how their version of LCoS avoids pitfalls other companies fell into. You'll also read postings made by people blindly opposed to LCoS, unthinkingly emotionally critical. These people are easy to pick out and discount. Early models of anything are more likely to have problems, and design and manufacturing improve as the production run progresses. No technology springs full blown, it must be developed and improved and there are failures along the way. Two years ago few people thought DLP would succeed, and now look how many companies have jumped on THAT bandwagon over the last year. Even though some people don't like it, and will denigrate people who buy it, the JVC D-ILA LCoS based units are successful, work, and are selling well. They will be one of a number of technologies available. It'll probably be 10 years or more before any one display technology (again) grabs over 50% of the market (if ever). Right now, I'd put my nickel on OLED displays doing that, but you can only get them in cell phones and PDAs today.
No display technology is perfect. People can choose their own trade offs. Saying any one technology is the one true holy grail, or another is trash (or worse) is like saying the only decent horse in a horse race is the one you bet on. Never mind different horses win on different days on different tracks.
