I read about a project to build a $100 (£50) laptop for children in developing countries, the non profit company will start making a $175 laptop with the aim to reduce the price to $100 over time. Its current price is $175, and it will be able to run Windows [possibly a version of XP costing $3 (£1.50)] in addition to its home-grown, open-source interface [Linux].
I hope the technology being developed in these project will become available to us to :)
