It's a threat Microsoft can't let stand: the entire third world learning Linux as children, and growing up to use it. And Microsoft is going to get its way.
It comes after a sudden wave of SCO-like problems for the OLPC project. A specious patent lawsuit over keyboards.

By refusing to tolerate hardware that runs another OS by default, Microsoft is working to reduce choice.
