Funny, I've gotten used to the advantages of NTSC compatibility and multiple
colors at 640x400x4, and for most of the images I am interested in at that 
resolution (I have no interest in 80x44 text screens however) the flicker
is virtually non-existant.  (if you don't believe me, send me an Amiga
disk and I'll send you some DeluxePaint files at 640x400x4 where you won't 
notice the flicker at all except on the DeluxePaint menus.  I can directly
video-tape these images, so if you'd rather see it on video, send me a
blank tape.

Now, again, the reason why I am posting this is not to annoy Atari owners
or to encourage the purchase of Amigas, but simply the hope that you
all will realize that everything is relative.  I *could* also say that
Atari will add a 640x400 NTSC mode to their otherwise great machine
if there is sufficient demand for it (but I won't).  How expensive it
is to make is only part of the issue, how compatible and flexible with
other real-world devices is part of it too.
