According to my multiplier, this is a screen resolution of 1575x1200 pixels -- a substantial information content. This is pretty good on all but the very largest of screens available today (which needless to say, are quite a bit bigger than 8" x 10.5").

Right you are. Lot's of pixels are nice to have, and so is a phyically big display.
Here we were talking about the minimal criterial to do scaling, pdf, readable fonts, etc., and here the pitch plus a few other things is what matters in order not to see artifacts. A display that would be the equivalent of two facing 10" high pages would indeed be about 4M pixels which is the count that Lex mentioned. But most paper notepads or xeroxed papers are 8.5*11 with not all the boundary pixels used, so my calculation covers this physical size.
BTW, in the late sixties we were able to compute pretty accurately that the proposed Dynabook (which was about 9*12), which employed its lower quarter with a low travel keyboard and had a squarish display, needed about 1M pixels in order to simulate paper well enough for readability, drawing, and capacity.
Cheers,
Alan

Dell's newest Inspiron laptop has a 15" screen that runs 1600 x 1200, 133 pixels per inch...
I have the next model down, which with a 15" screen runs 1400 x 1050, which is 117 pixels per inch, and I love it.
Later, Jon
