Maybe but I have seen 300dpi printouts with grayscale antialiasing that
looked very very good. Remember we are talking mostly text and line
drawings here (the op was referring to reading magazines online). Since
Spehro uses a lot of PostScript he should know. Maybe he wrote what he
wrote because he does know. Anyway a paper white high resolution monitor
is much easier on the eyes than a 0.21 dot color monitor, even if run in
B/W, and the resolution limit is much higher than for color.
