The XO-1 is the first version of the One Laptop Per Child. It comes in compact (242x228x32 mm) and rugged green package, with an innovative screen (7.5 inch), a membrane keyboard (sized for children), a touchpad with adjacent stylus areas (reserved for future use), three USB ports, an internal SD card reader, a built-in microphone, speakers and video camera.

The computer is powered by a 433 MHz AMD CPU that runs at only 800 mW, the display uses between 100 and 1000 mW, so that the overall power consumption is less than 3 W. It does not come with a hand-crank, but a selection of hand- or foot-operated power units is optionally available.

Networking is an important part of the educational concept behind the project and the XO-1 sports a Wi-Fi chipset that allows connections using 802.11 with an access point or by forming an ad-hoc mesh network with other XO-1. The latter allows sharing a single Internet connection for a the whole classroom.

All software on the XO-1 is free and open source. The operating system is based on Fedora Linux and a Python-powered GUI called Sugar. A central component is the Journal, which keeps a chronological logs of all activities, such as changed files or accessed applications, and allows to resume those activities (open the file or application again). The bundled software is mostly educational programs to encourage creative exploration into the realms of music and programming, but there is also a general purpose (Mozilla-based) browser, a word processor, and an RSS reader. I could not find a scheduling application, or even a calendar, though, clearly it is not aimed at business people.
