       ... so I take out my ruler and make some measurements...
For myself, the optimal viewing distance for a terminal (even at 132 columns)
is between 2 and 2-1/2 feet. Moving back an extra foot in no way necessitates
the use of 'long sticks', and the mouse already has a sufficiently long cord.
(okay, I know, tongue in cheek 8-)) If I had wanted a paperwhite monitor, I
would have bought that, but not 70Hz - that will not work with the Amiga,
or as a TV.

What you probably saw was a demo shown under high ambient light conditions.
This means that the monitor brightness was cranked up to full. The persistence
of the phosphors effectively decreases when this is done. I use the (Sony)
PVM1271Q at about 1/2 the maximum brightness in a room with low ambient light.
(I have a desk lamp to provide more light where it is needed). As I stated
previously, hi-res graphics look very good. In fact, I have found that most
people are quite impressed by the lo-res graphics, and find the flicker in
hi-res far from 'unbearable'. I have not been able to test this, but I
firmly believe that hi-res animation, with a full screen, will show no flicker
at all. Why should it? (any more that a normal TV does anyway)

I bought an Amiga partly because of NTSC compatibility. Frame grabbers
and gen-lock are a natural extension to the machine because of the
compatability, something which will make similar additions much more
complex (and expensive) for other (unmentionable) machines.
