The main point of contention revolves around Intel’s continued support of Classmate, the company’s own low-cost computer for kids in struggling countries. Negroponte says that Intel’s aggressive marketing of its Classmate included badmouthing the XO. “We had a nondisparagement agreement,” says Negroponte. “I was not allowed to say [negative] things about Intel, and they were not to disparage OLPC. But instance after instance, they violated it. It became untenable.” Asked for examples, he says that after OLPC concluded a deal to sell 270,000 laptops to Peru, Intel officials went to government officials and warned them that his XOs wouldn’t work. Since Intel was on the OLPC board, such charges carried more credibility than a normal competitor’s, says Negroponte. After complaining to Intel CEO Paul Otellini, Negroponte says the disparagement didn’t stop. Negroponte told Intel that it would have to cease producing the Classmate (though it could license the platform to other manufacturers if it wished) if it wanted to stay in the OLPC program. Instead, Intel decided to bail, as Negroponte found out this week when Intel told The Wall Street Journal about its decision. “I heard it in a taxi cab,” he says.

From Intel’s viewpoint, the dispute boils down to “a philosophical impasse,” says spokesman Chuck Mulloy. The company, he says, strongly believes in the concept of low-cost computers for Third World kids, but also feels that there should be multiple vendors to serve this marketplace of more than a billion potential users. “They wanted us to focus exclusively on the OLPC platform,” says Mulloy. Such an approach, he says, was not only undesirable but was also impossible for Intel, which could not break commitments with other manufacturers, software developers, and governments buying into the Classmate. As for breaking the disparagement clause, he says, “We’re confident that we were in compliance with the contract.”

Assigning blame depends on whom you believe. Negroponte charges that “it certainly feels like [Intel] didn’t enter into the agreement in good faith.” Intel, through its spokesperson Mulloy, says, “We disagree. We have acted in good faith.”

The harm to OLPC, says Negroponte, was that working with Intel drained its limited resources and distracted his organization from its mission. “We spent a lot of effort trying to make this work,” he says. This is just one of a series of setbacks suffered by OLPC since Negroponte, at the 2005 World Economic Forum in Davos, captured the world’s imagination with the promise of a hundred-dollar laptop. Though OLPC is finally shipping the green-and-white XO (not at the $100 cost, but with a price tag of $188), some countries have canceled their million-unit purchase plans. Negroponte, who originally wasn’t planning to sell the unit to Americans, changed course this fall with a “Give 1 Get 1” program. (More than 80,000 people paid $400 each to buy a laptop for themselves and one for a needy kid.)

Negroponte is in this for the long haul, and his main asset is the XO itself. I have played with both the OLPC’s XO and Intel’s Classmate, and I think that for the purpose of seeding developing countries with new technology, there is no comparison. The XO, built from scratch to directly address the unique challenges that such a device faces, is infinitely more imaginative, easier to use and forward-looking than the Classmate, which costs more and runs Windows. (“Intel’s own people tell us Classmate is a dog,” says Negroponte, obviously no longer committed to his nondisparagement clause.) While the Classmate does come with specialized network software for classroom situations, the XO is brimming with innovations, from its rugged industrial design and stunning works-in-sunlight screen to its low power consumption and powerful Wi-Fi antenna. As with any new device–particularly one created by an entity with little manufacturing experience–there are snags. But it’s a breakthrough device that deserves to make its global mark.

“We are going to explore ‘OLPC America’–starting yesterday,” says Negroponte.
