It's been four years since the The One Laptop Per Child (OLPC) project (known then as the '$100 laptop) was announced. According to recent unconfirmed news reports from India, one quarter million of the little green and white OLPC XO laptops are now on order for use in 1500 hundred schools on the subcontinent. Four years on, what have we learned about the impact of various OLPC pilots that might be of relevance to a deployment in India? Thankfully, preliminary results are starting to circulate among researchers. While nothing yet has approached what many consider to be the gold standard of evaluation work in this area, some of this research is beginning to see the light of day (or at least the Internet) -- and more is planned.
