XO-4 Touch Convertible Laptop
XO laptops use a custom Red Had Fedora OS running the Sugar user interface. Starting in 2007, they were powered by x86 CPUs but were switched to ARM chips in 2013 with the XO-4 Touch. The XO-4 has 1 or 2GB of RAM, 4 or 8GB of solid state storage, USB ports and Bluetooth, and its Wi-Fi mesh configuration can interconnect an entire village. A key design factor was the unique, 7.5" dual-mode display that enables black and white viewing in bright sunlight.
In 2013, the XO tablet replaced the XO-3 tablet/e-book project that never came to fruition. Available at retail outlets, the tablet is Android based with 1GB of RAM and 8GB of solid state storage. For more information, visit www.xotablet.com.

The XO Tablet
(One Laptop per Child, Cambridge, MA, www.laptop.org) A research initiative of MIT Media Labs devoted to the creation of a USD $100 PC for educating children in developing countries around the world. Founded in 2005 by Nicholas Negroponte, OLPC laptops are geared to the educational ministries of governments that can purchase thousands of units at a time.
Taiwan-based Quanta Computer was selected as the original design manufacturer (ODM), and manufacturing began in late 2007. Although USD $100 was the target, a manufacturing cost of about $190 was announced for the first run of 300,000 units, a smaller order than anticipated.
Although orders for millions of OLPCs were expected by 2007, Intel persuaded several countries to use its own low-cost PC (see Classmate). Negroponte admonished Intel for interfering with his non-profit venture to help the poor. Soon after, Intel joined OLPC's board to help design future products but withdrew in 2008. For details about OLPC models, see XO computer.
