I do a talk in which many technologies are plotted on semi-log-scale
charts, with the vertical axis performance/capacity/bandwidth,
plotted versus year.  If two technologies are plotted on the same chart,
and they are improving in parallel, they tend to get used the same way,
with the same tradeoffs.  If the ratio is changing, then the tradeoffs
keep changing.  Example:
	Hennessy & Patterson, 1st edition, had a problem where one was
	asked to calculate the year when one would throw away disks in favor
	of DRAM, since the former was increasing in density at ~2X/3 years,
	and the latter at 4X/3 years, both at approximately-cosntant price.
	Then, disks accelerated to 4X/3 years, and the problem disappeared
	from H&P's second edition.

CRTs have been around a long time: does anybody have a table they
can post, over last 10 years, of some kind of normalized price for each
of several size/resolution combinations?  My sense is that prices haven't
been coming down all that fast, especially for larger monitors. (?)

Good LCDs are fairly new; I used to check out overhead displays at every trade show, and was usually disappointed.  I rememember how excited everybody was,
~late 1993, when we had the earliest Indy Presenter flat panels (1024x768),
but they were only avaialble in tiny handfuls from the display vendors.
(Everybody was excited, because the earlier panels were OK for static graphics,
but fairly useless for motion, and these were actually OK, finally).

The moral of all this:
	(a) Big flat panels are still expensive.
	(b) But, they are moving fast, and things are now available at
	reasonable (if not cheap) prices that weren't available in any
	reasonable form just a year ago.
	(c) Hence, without knowing anything about the pricing on this specific
	product, on general technology grounds, anybody would expect that
	the current price is for a brand-new, premium product in its earliest
	phases, and that the prices of such products will come down.
	(d) What is certainly true is that we are now actually starting to
	get LCDs with display size, persistence, color characteristics that make
	them reasonable to do serious graphics with, which was just not true
	at all not very long ago.
