As an aside, I used to actually quite like the effect of a CRT at
resolutions above what the dot pitch said it could handle. So long as it
didn't bring down the refresh rate, the low-GPU fake antialiasing in games
looked fine, just like my 640*480 console looks less pixelated on a 23 inch
TV than my 1280x1024 computer does on a 19 inch monitor.

Hmmm... what is the current state of vector interfaces? I think I read
somewhere GNOME uses lazy rasterised SVG for all icons etc. I might have
been reading about a future version, mind.

Maybe future very high res screens are where Opera will gain greater use,
because it can zoom the bitmapped parts as well as increase the text size.
