If screen real estate ranks higher on your list than graphics performance, a couple of these USB video cards could be a nice addition to your workstation. They’re from a sister company of Buffalo named Kuroutoshikou and are available with either a DVI or RGB video connection.

They’re both capable of displaying either 1440×900 (WXGA+) or 1280×1024 (SXGA) on a separate monitor and besides a USB 2 port, you’ll also need a system with at least a 1.2GHz PIII and a half gig of RAM. What’s particularly cool is that you can actually add up to 6 of these devices to one computer, though your system requirements jump up to a 1.6GHz Core Duo machine with 1Gb of RAM, and don’t expect to use any of the fancy 3D effects in Vista’s Aero theme either.

The USB video cards should be available in Japan in late December and will range in price from about $81 to about $107.
