This MacBook Air is running four screens simultaneously. Its own, a 20-inch Apple Cinema Display, a 7-inch Mimo 720-S USB display and an Apple IIc running a terminal session through a serial cable. For an underpowered notebook, that's quite a feat.

And yes, the Apple IIc is kind of a trick, but it does run off the MacBook Air's Unix soul. [Blakespot via Unplggd]
