The One Laptop Per Child project team today said it was stepping up the schedule for its XO-3 tablet. The touchscreen, sub-$100 tablet is now due to have first appearance at CES 2011, two years ahead of schedule, but will shed some of its original ambitions to get to that point. It should instead be based on Marvell's Moby platform and use a 1GHz ARM processor; the design won't use an all-plastic, waterproof shell and should be thicker than the quarter inch set out earlier as a target.
