I find nothing irritating about the color of plasma displays.  Perhaps
you are letting some cultural bias show through.  I have never had
problems with them in over 2000 hours of gas-plasma panel use on the
PLATO system.

One nice advantage of a plasma panel is that you can project pictures
onto it, but this advantage is probably being superceded by LCD
displays.

I don't know why a limited brightness control is impractical in in
principle.  Generally, plasma displays are pretty bright under strong
flourescent lights.  I don't know of any terminals that do well in
direct sunlight.
