Nicholas Negroponte, founder and chairman of the One Laptop Per Child non-profit group, revealed big news about his laptop for the poor children of the world. His biggest revelations: The laptop will run Windows, and the group is seriously considering selling it in the United States.

The machine, which OLPC aims ultimately to price at $100, is called the XO.

But now Intel’s longtime animosity to the project has taken on new intensity, and that has consequences. Negroponte asserts that in the last couple of weeks, as the final deadline of May 30 approaches for countries to make firm commitments for XOs, Intel has been methodically going to the expected launch countries and offering unusually attractive terms for its own much-less-sexy Classmate PC.

The Classmate is essentially a standard but simplified desktop that like the XO is decorated in green plastic, but less fetchingly. Negroponte claims Intel is pricing it at $180, significantly below its cost of production, and for lots of only 10,000. In an email, Intel spokesman Bill Calder responds that the Classmate’s price is generally higher and he’s not sure what Negroponte is referring to.
