XO-1

The XO-1, previously known as the $100 Laptop or Children's Machine, is an inexpensive laptop computer intended to be distributed to children in developing countries around the world, to provide them with access to knowledge, and opportunities to "explore, experiment and express themselves" (constructionist learning). The laptop is developed by the One Laptop per Child (OLPC) non-profit, 501(c)(3) organization and manufactured by Quanta Computer.

The laptops are designed for sale to government education systems which then give each and every primary school child their own laptop. Pricing was set to start at US$188 in 2006, with a stated goal to reach the $100 mark in 2008.

The rugged, low-power computers contain flash memory instead of a hard drive and use Linux as their operating system. Mobile ad-hoc networking is used to allow many machines to share Internet access from one connection.

This laptop helped to define the emerging (2007) category of Netbooks.
