The XO-1, previously known as the $100 Laptop, Children's Machine, and 2B1, also nicknamed ceibalita in Uruguay, is an inexpensive subnotebook 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 subnotebooks are designed for sale to government-education systems which then give each primary school child their own laptop. Pricing was set to start at $188 in 2006, with a stated goal to reach the $100 mark in 2008 and the 50-dollar mark by 2010 . In actual implementation, prices have remained $199 each for both the winter (northern hemisphere) 2007 and winter 2008 Give One, Get One campaigns (and thus $398 per pair).
