But "years ago", and in fact on the monitor I'm currently using, the
pixels can be seen. (When I put my eyes 6' from the screen and wear
my reading glasses; I assume younger members of our chevrah can do it
with their naked eyes.) Your typical monitor, even today's LCDs max at
around 85 pixels per inch (ppi), and those CRTs that R' Gustman spoke of
"years ago" were around 67 ppi.

Another difference with e-paper, other than the permanence, is that this
isn't true. I don't think the typical person can see the pixels at 150
ppi. Similarly, the pixels on an iPhone or iPod (362 ppi), and probably
not even an iPad (132 ppi).
