Unless you have been living under a rock, you have probably heard of the One Laptop Per Child foundation.

Their goal was to develop a $100 laptop (Called the XO) and give it to children in developing countries . The project was highly heralded and many governments signed on to buy thousands of these laptops.

Part of the concept was to use Linux as the base operating system. The end result was a interface called "Sugar" that was unlike any known computer interface in the developed world. Written in Python, it was definitly unique, though some people find its UI strange and counterintuitive.

After all the fanfare, the foundation was not able to meet the $100 goal, and is now offering the laptop for close to $200.
