Brazil's Linux PC
Brazil's first official stab at a low-cost, Linux-powered computer for the masses was the Popular PC, in an initiative launched in 2001. Many components, including a flash drive, were to be built domestically to avoid high import taxes, but the project never got off the ground. That version was to cost around $250. A subsequent version of the Popular PC used a more conventional architecture that pushed the price tag to the neighborhood of $600. The program went into limbo in 2002 with a change of government.
The Personal Internet Communicator
Designed by Advanced Micro Devices, the Personal Internet Communicator runs on a version of Windows CE and an energy-efficient processor. The machines cost about $180 without monitor--not that much cheaper than a full-fledged PC with monitor. They've been released in India and the Caribbean, but sales have been tepid.
