Photos: Little box outfoxes spam

The Spam Cube, which comes in white, black, silver, pink and yellow, is one of the first antispam hardware appliances for individuals--and it requires no monthly fee. It's due to launch in April.

The $150 Spam Cube is relatively minute, although it could be even smaller--most of the cube is empty. The real hardware is a square circuit board at the bottom of an otherwise empty plastic cube.
