Speaking as a tv engineer, due to the LCD manufacturers (most of the higher band makers like Sony, Panasonic, Philips etc..) only supply boards to repair their sets. Which means repair costs are VERY high. So if you opt to go for LCD, make sure you have plenty of insurance. Although LCD tvs are getting better in both quality of detail and brightness level output, i still prefer the old old CRT anyday!...

I heard CRTs have a lifetime of around 8,000 hours. They usually die by the cathode material on the red gun wearing out and causing red parts of the image to go dim and blurred. You can tweak the brightness back up, but the picture still looks blurry, and no amount of twiddling the focus helps. I lost count of the number of old TVs and monitors I did this to over the years. When I think about it, I should have tried the trick of boosting the filament voltage.
LCD backlights wear out too, but they're easy to replace.
I much prefer LCD monitors for computer use, there's something about the picture quality that makes it almost restful to look at. But for TV and video use, it's not so clear-cut.
The one thing I hate most, though I'm not sure it's on topic, is watching DVDs on a PC: no matter how fast the machine, panning shots always seem to jitter and jump. I think it's due to the difference in refresh rates between the PC graphics card and the DVD video stream. I think the best DVD playback I ever got was on one of those old Hollywood+ hardware decoders, when I followed its recommendation to set the refresh rate to 75Hz.

As a broadcast engineer I'm always looking at picture quality and nothing I have ever seen has ever beaten a CRT, LCDs can come close but as soon as there's movement it blurs horribly. What I'm getting excited about is the new SED technology (Surface-conduction Electron-emitter Display), basicaly CRT quality but as thin as LCDs and plasmas. http://www3.toshiba.co.jp/sed/eng/about/index.htm Unfortunatley these won't be around until next year. Richy.
