Engadget writes, "Last time we spied the XO-3 tablet concept from OLPC, we were told to expect the thing to ship in the far-distant year 2012. Much has changed since then in the tablet arena, however, and Nicholas Negroponte, the project's founder, is saying they'll have a working prototype ready by December of this year, to be shown off at CES in January of 2011.
