XO-4 Touch Convertible Laptop
The Linux-based XO laptops use a custom Red Had Fedora OS running the Sugar user interface. Starting in 2007, they were powered by x86 CPUs but switched to ARM in 2013 with the XO-4 Touch. The XO-4 has up to 2GB of RAM and 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.
