Well, it's debatable that CRT is the best technology in many situations. First of all, the size is limited. While Sony concatenated multiple tubes in their early Trinitron days, you won't be getting a 60" (or even a 42" as far as I know) CRT television any time soon (or more likely ever). Also, the grain on the individual pixels on a CRT are normally larger at the same screen size than plasma or LCD these days. Then, of course, there's weight and bulk. In the end, CRT really isn't all that hot these days for multiple reasons. *shrug*

As for Plasma televisions, there's also the issue of burn out, as was mentioned. That is one area CRTs shine... they last damned near forever if they are good quality and taken care of (at least forever in terms of electronics). Plasma's seem to be at the bottom of the barrel. They burn out a bit faster (average) than LCDs and only some can be "recharged" which comes at a pretty hefty expense and also does not restore the original sharpness of the display. LCDs also burn out, but most (and ALL Sharp's FYI) have a servicable backlight (which is just a flourescant tube anyhow), but they do so after a higher number of use-hours and the "fix" is cheaper. On top of that, a new bulb, after recalibrating your TV (or making your own adjustments) will literally be as good as new since the liquid crystals themselves do not degrade.

The primary downside to LCDs used to be viewing angle, which really isn't an issue now. On my display, I can sit at roughly 45-55 degrees off center (giving a roughly 90-110 degree angle) without any dropoff in contrast. After that it's only contrast, and not much. The sharpness is still sweet. The other LCD issue are frozen/stuck or dead pixels. Frozen pixels are relatively easy to fix these days. Dead pixels are sometimes pixels that are frozen in the black stage and are fixable as well. A truly dead pixel does suck, but it happens relatively rarely.
