The XO-2 will be designed to consume less power and be half the size of the original XO. In addition to its open source Linux-based OS, the machines will carry a dual boot option for loading Windows. The OLPC group argues the falling price of flat panel screens will make the costs achievable. And, in addition to the new model, Negroponte announced the return of the Give 1, Get 1 program in which U.S. customers will be able to buy a laptop for a child in the developing world at the same time as they buy their own. But skeptics are already questioning the viability of the ambitious design and price point, given the XO’s history of struggling to meet its goals so far to date. Via BBC
