The OLPC XO, previously known as the $100 Laptop,〔 Children's Machine,〔 and 2B1,〔 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 manufactured by Quanta Computer and developed by One Laptop per Child (OLPC), a non-profit 501(c)(3) organization. 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.〔 When offered for sale in the Give One Get One campaigns of Q4 2006 and Q4 2007, the laptop was sold at $199.〔 These rugged, low-power computers use flash memory instead of a hard drive, and come with an operating system derived from Fedora Linux as their pre-installed operating system with the Sugar GUI.〔 Mobile ad hoc networking via 802.11s WiFi mesh networking is used to allow many machines to share Internet access as long as at least one of them can see and connect to a router or other access point. The latest version of the OLPC XO is the XO-4 Touch.〔http://wiki.laptop.org/go/XO-4_Touch〕 == History == (詳細はNicholas Negroponte and then-United Nations Secretary-General Kofi Annan on November 16, 2005, at the World Summit on the Information Society (WSIS) in Tunis, Tunisia.〔 The device shown was a rough prototype using a standard development board. Negroponte estimated that the screen alone required three more months of development. The first working prototype was demonstrated at the project's Country Task Force Meeting on May 23, 2006. In 2006 there was a major controversy because Microsoft had suddenly developed an interest in the XO project and wanted the formerly open source effort to run Windows. Negroponte agreed to provide engineer assistance to Microsoft to facilitate their efforts. During this time, the project mission statement changed to remove mentions of "open source". A number of developers, such as Ivan Krstić and Walter Bender, resigned because of these changes in strategy.〔〔〔 Approximately 400 developer boards (Alpha-1) were distributed in mid-2006; 875 working prototypes (Beta 1) were delivered in late 2006; 2400 Beta-2 machines were distributed at the end of February 2007;〔 full-scale production started November 6, 2007.〔 Quanta Computer, the project's contract manufacturer, said in February 2007 that it had confirmed orders for one million units. Quanta indicated that it could ship five million to ten million units that year because seven nations had committed to buy the XO-1 for their schoolchildren: Argentina, Brazil, Libya, Nigeria, Rwanda, Thailand, and Uruguay.〔 Quanta plans to offer machines very similar to the XO-1 on the open market.〔 The One Laptop Per Child project originally stated that a consumer version of the XO laptop was not planned.〔 The project later established, in 2007 the laptopgiving.org website for outright donations and for a "Give 1 Get 1" offer valid (but only to the United States, its territories, and Canadian addresses) from November 12, 2007 until December 31, 2007.〔 For each computer purchased at a cost of $399, an XO is also sent to a child in a developing nation.〔 OLPC again restarted the G1G1 program through Amazon.com in November 2008, but has since stopped as of December 31 (2008 or 2009).〔 On May 20, 2008, OLPC announced the next generation of XO, OLPC XO-2〔 which was thereafter cancelled in favor of the tablet-like designed XO-3. In late 2008, the NYC Department of Education began a project to purchase large numbers of XO computers for use by New York schoolchildren.〔 The design received the Community category award of the 2007 Index: Award.〔〔 According to Computer Aid International, in a test conducted in April 2009, the device was ranked as the most power saving among other information and communication technologies in education solutions.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OLPC XO」の詳細全文を読む スポンサード リンク
