Well, I don't know how they're going to figure out how to distribute them - or keep them from being stolen and sold for parts, or defend them against viruses. Yes, viruses. They're not worthwhile targets for people who want bank account info or a node for their botnet, but you can bet some asshole is going to try and ruin the party. Although the computers are running Linux, so that might not be so much of a problem.

As for the other issues, the developers of the laptop have taken great care to address them. The computers come with all of their software preinstalled, and since they're simple machines meant only for word processing and Internet access, there isn't a lot to put on there or mess up. The OS is also designed to be easy for kids to use and figure out. With perhaps a day's training the kids can learn how to work the computer and how to recharge it with a special foot pedal or something. And keep in mind, these will be kids who are very interested in learning how their shiny new computer works.
