Matrox has a new dongle that takes the VGA output from a desktop or laptop computer and splits it into two DVI outputs running at 1920x1280 each. This could either trick a single-head Windows or Mac into running two displays or an existing dual head setup (like most Macs) into running three displays. That's a lot of pixels for a (relatively) low cost.

Only $229 (plus, obviously, the cost of the monitors).
