MIT Media Lab unveiled a working prototype of the $100 laptop at WSIS in Tunis, last week. The project, as reported before, will bring computing en masse to less developed areas of the world. More information and specs is now also available.

Apparently, Steve Jobs of Apple Computer offered his latest operating system to the project for free, but was turned down by the Nicholas Negroponte, chairman of the project, who opted for strictly open-source software.
