For those of us who love to have an array of monitors to form our ultimate computer setup, but are limited to 2 displays by our video card. Or at most 4 if you have 2 video cards. You can always add more with USB display adapters like this one from OWC. This USB display supports upto 6 VGA/DVI/HDMI displays and is self powered and uses low CPU load. I know I can do with 6 displays to play my favourite games! $99 at OWC.
