The One Laptop Per Child $($OLPC$)$ project intends to create a $$100$ laptop for distribution to the world's poorest children. The machine, called the OLPC or XO laptop, has a rubberized keyboard and an ultra$-$ bright screen readable in daylight; when flipped, it converts to an electronic book reader. To keep the cost as low as possible $($at $$175,$ it is currently a bit more than the target$),$ the computer has a host of free software and other tools to support learning opportunities. A special type of networking allows machines within $100$ feet or so to communicate with each other and relays a single Internet connec$-$ tion for them to use $($where the Internet is available$).$ The XO is targeted at communities where power generation is unreliable or nonexistent; it gets its power via a hand crank, pull cord, or foot pedal$\mathrm{.}19$
