The former CTO of the One Laptop Per Child initiative, which builds inexpensive notebook computers for kids in developing countries, now plans to build an even cheaper version. Mary Lou Jensen hopes to succeed where OLPC failed: She wants to produce laptops that sell for under $100. Way under, in fact. She says she should be able to commercialize one with a price tag of only $75. Given that the price of the OLPC version is currently north of $180, this might sound unrealistic.
