Small laptops have been hogging most of the limelight lately, but Dell's tiny new PC could bring attention back to desktops.

Dell CEO Michael Dell on Tuesday previewed what he called "the company's smallest and most environmentally-responsible consumer desktop PC." Dell previewed the desktop as part of Earth Day at the Fortune Brainstorm conference being held in Pasadena, California.

The small form-factor desktop is 81 percent smaller and uses up to 70 percent less energy than a typical desktop mini-tower, said Anne Camden, a Dell spokeswoman.

She declined comment on hardware specifications, brand name or pricing. Details will be released later this year when the desktop is released.

The desktop, which stands on a holder, will come in recycled and recyclable packaging, Camden said.

It will most likely compete with Apple's Mac Mini and Everex's MyMiniPC, mini desktops with full computing capabilities designed to save desk space.
