I disagree here.  If you look at an Amiga in the interlace mode or a IIgs with
a video overlay card significant jittering of the image occurs because of 
interlace.  Long persistence phosphors help as does turning the brightness
down and darkening the room (the poor mans way of increasing the relative
persistence of the phosphors).

For some reason, some people notice this more than others.  It
really annoys some people.  Maybe Apple can come up with a method of allowing
interlace on low cost monitors while letting monitors with greater bandwidth
show the screen in non-interlaced mode.
