I agree about DVST's, I threw that in for a bit of history (I worked as an
design/development engineer at Tektronix for about 15 years, although not 
in the display or printer divisions).  I dumpstered the last of my personal
DVST display units (among massive other things) when I finally moved earlier 
this year.

As to the flat panel displays, I suspect a significant number do use just that 
when they use their laptop computers which are VERY commonly used.  I only 
mentioned that they were starting to invade the desktop for those who didn't 
notice their coming.

Here at work I have the cylinder-shaped Trinitron tube type display.  I've
got an upgrade coming -- a new Sun workstation with a 24" display.  I'm not
sure what kind of CRT the new display will have.  Should be installed soon
so we'll see.  :-)  

Does the radius of the curve vary with screen size?  On my current display,
(21" I think) it doesn't curve as much (horizontally) as I seem to recall
seeing smaller trinitrons having.  Or maybe it just seems that way?
