I second the call to not assume 1 pixel per point and 72DPI. After
all, what would happen if you're presented with display with much
greater pixel density? Drawing individual pixels then can result in
tiny images.
Check out this monitor, for instance:
http://www.viewsonic.com/products/desktopdisplays/lcddisplays/
proseries/vp2290b/
A 22.2 inch display with an astounding 9.2 megapixels - that's
3840x2400, or roughly 5x the pixel density of most LCDs - over 200DPI.
The reports I've heard is that this is a great monitor, but the common
complaint is that desktop displays are tiny - text and window furniture
is drawn so small it's difficult to see. It would make a great deal of
sense for a desktop to be rendered at a higher DPI level on screens
like this. I would not be surprised if Quartz was capable of drawing
at a higher resolution already.
Yes, at $6k it's damn expensive, but other displays are coming that are
similarly high resolution - Sony's Librie e-book reader for example has
a Philips display that's about 170DPI, and it's a lot cheaper at under
$400.
