$100 Laptop
MIT has put together the specifications for a computer that should cost no more than $100 to build. The 12 inch laptop computer has wireless networking, six usb ports and a shoulder-strap that doubles as a power cord. The computer would be built primarily for third world countries looking to introduce computers into the classrooms of their students. Given this, the computer also features a small crank which can be used to provide juice to the computer in areas without handy electrical power. The computer may be produced commercially for developed nations and would likely run around $200 with some of the proceeds going to the effort to get these computers, again, into more povershed areas.
