Nicholas Negroponte, co-founder of the MIT Media Lab and member of Motorola's Board of Directors, wants to build a $100 laptop to distribute (not sell individually) to children in the developing world. The premise of this endeavor, which will require technologic innovation as well as significant financial committments from governments to purchase these computers, is that such a device would provide children a tech-based leveraged education and enable them to better learn and succeed in a globalized world.
Some folks, such as Bill Gates, seem to think the idea is not worth the effort. Google apparently disagrees. One common critique of such enterprises is "This money could be better spent elsewhere (on food, vaccines, bednets, etc.)" or what might be called the Transitive Argument (refer to your math textbooks prn). I do not fully prescribe to this argument, because I am not always convinced that money which does not go to one thing would have gone to another.
Time will tell if the $100 laptop turns out to be just a fanciful idea or one that does begin a small revolution in education. Regardless, this type of project has captured the imagination of a group of people who might not otherwise be as engaged in thinking about solutions to the world resource gap, and this fact alone is perhaps enough to earn the initiative some level of support.
