Just attempting to distribute millions of laptops to children in the developing world is ambitious enough. But Nicholas Negroponte, the founder of non-profit One Laptop Per Child (OLPC) in Cambridge, Mass., has always had a grander vision. Four years ago, the MIT professor announced plans to build a durable, human-powered laptop for $100, heralding the rise of ultra-cheap netbooks. Now, Negroponte has a new mission: to build a $75 tablet computer that is waterproof, flexible, thinner than an iPhone and made entirely of plastic. |
