英特爾與OLPC攜手生產100美元電腦
一些學童使用OLPC開發的100美元電腦
英特爾與OLPC（一兒童一電腦計劃"，又稱人人電腦計劃）達成協議，共同生產價格約100美元的手提電腦，向貧困的兒童推廣電腦教育。
美國麻省理工學院尼古拉斯·內格羅蓬特教授發起的非牟利的OLPC曾遭到一些電腦廠商的對抗。
內格羅蓬特在今年5月公開批評電腦芯片生產商英特爾阻止OLPC的發展，應該對這一行動感到慚愧。
他指稱英特爾以低於成本價傾銷其"Classmate PC"型號的手提電腦，目的是希望把OLPC趕出發展中國家的電腦市場。
英特爾發言人說，過去的事情已經過去了，現在要向前看，有關協議將可讓英特爾和OLPC做得更好，並會在雙方都極希望做的事，就是幫助全世界兒童，取得更大的影響力。
OLPC的始創人內格羅蓬特教授現在說，英特爾作為世界科技界的領導者，成為OLPC的一份子，將有助於向全世界兒童提供最大數量的電腦。
根據協議，英特爾將與Google(谷歌)、紅帽（Red Hat）等11家公司共同推動OLPC計劃。
在此之前，OLPC打算採用英特爾的商業對手AMD公司生產的處理器。
"全世界兒童受惠"
AMD公司發表聲明說，該公司對英特爾改變初衷表示歡迎，並相信英特爾將為有關計劃提供積極的貢獻，"讓全世界兒童受惠"。
據信，OLPC仍採用AMD的處理器，但支援手提電腦的服務器將使用英特爾的技術。
英特爾的“Classmate PC”手提電腦售價約200美元
OLPC說，會考慮在將來使用英特爾的芯片製造電腦，同時，OLPC生產的"XO"型號手提電腦和英特爾生產的"Classmate PC"將可共用操作系統軟件。
OLPC的手提電腦的初步價格是176美元，最終目的是以100美元的價格賣給發展中國家。
英特爾表示，現在已接到數千台"Classmate PC"的訂單，目前的售價是200美元，但預計將可進一步降低售價。
