One approach to the resolution question is to ask how many patterns you
can have subject to various constraints. It particular the logarithm base
two of the number of patterns is an interesting measure of the effective
resolution. On a 200 line monitor, you can have 2^200 patterns (when using
two colors, such as black and white); on a 400 line monitor, you can have
2^400 patters. The logarithm is 200 and 400 in the two cases. If you require
one of the colors to occur in groups of atleast two (as was suggested for
reducing flicker) you can have about 2^324 patterns in 400 lines for an
effective resolution of 324 lines. If you require both colors to occur
in groups of atleast two, then the effective resolution is about 278 lines.
This suggests you should be able to control the flicker on the Amiga and
still get some what better resolution than the Atari, but only a little
better.

The above calucations, of course, are just suggestive, and if you have a
particular application such a displaying text, there is no substitute for
display text in the best way you can and then look at how good of a job you
were able to do.

By the way, I have an Atari. I could not see paying twice as much for a
computer that was only slightly better.
