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.

XO Tablet
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.
