The One Laptop Per Child project's long-in-waiting XO-3 tablet, now called the XO 3.0, will get its formal unveiling at CES. The eight-inch, 1024x768 slate will have a ruggedized body to survive rural schools and, like the original notebooks, consumes very little power. OLPC notes that it can take energy from a solar panel and that a hand crank can give it 10 minutes of power for every minute of turning, letting it work even in remote areas where electricity isn't guaranteed.
