A Wired News interview with Nicholas Negroponte. A couple of points:
… Wired News: The machine is expected to start mass production late next year, and the governments of Thailand and Brazil have already said they’re serious about placing $1 million orders for their school kids. Others are close to lining up.
… Negroponte: Clearly (though) in some countries even $100 spread over five years is too expensive. So in those countries we have to find other means to pay for it than the normal education budget. But at least half of the developing world — certainly half the population, probably half the countries — could afford the $20 per year.
