So Sewell is releasing a USB to DVI adapter in the near future (available for preorder only now). This means you can take a video card with you to add an additional display to a laptop or desktop easily. It’s actually quite ingenious. For desktops, you don’t have to rummage around in your case to install new hardware (luvs me that plug and play!). Plus, it’s portable enough that if you wanted to switch a display from notebook to desktop or if you want to use the same device with multiple computers (not simultaneously obviously), you can do it easily.

The adapter boasts 128 MB of RAM which is enough to drive a display up to 1400×1050. And, I got to test one. It looks really good. There just aren’t many comparable products, either, if you want an additional display without doing a full product install. Pics below.
