   There could have been a point about refresh rates. I used the original   
   small-screen Macintosh a lot in the mid-1980s, which as you know used a   
   light background when everybody else was still dark, and that had a 60Hz   
   (actually 60.15Hz) refresh. It was fine when I looked at it directly, but   
   I could see the flicker in my peripheral vision.   
      
   Then I went to a Macintosh II, with a bigger screen (13” or 14”, depending   
   on how you measured it), with a 67Hz refresh. That higher rate worked well   
   at that larger size.
