I'm using a 22" HANNS G monitor and usually browse the web at 1024x768 pixels, which gives me an exceptionally comfortable, richly-rewarding display that my sad old eyes don't have to squint in order to focus on.
Having read your idea I cranked my Nvidia 8800GT up to 1680x1050 pixels and... [b]WOW!! WHOA!![/b] ...I suddenly had a rush of Vertigo. Tiny typefaces all crowded into the middle of the screen. Don't get me wrong - I play Crysis Warhead at this resolution but that's a game, not a browser window.
In fact, I take back the comment about the binoculars, you'd actually need a rather strong Microscope!! :^0
