OLPC's XO 3.0 tablet has been in the works for what seems like forever, and now it's finally ready to be unveiled at CES. Nicholas Negroponte apparently either found the unbreakable screens he was looking for or simply decided the crowds at CES 2012 should get to see the new slate first. It's powered by a Marvell ARM PXA618 SoC that runs Android or Linux and has the same Pixel Qi display seen in other OLPCs. Plus, it has special charging circuitry so it can top up its battery using solar cells and hand crankslike its XO 1.75 sibling -- a particularly useful feature in places where electrical sockets are hard to come by. Unfortunately, pictures of the tablet are still scarce, but come on back next week when we get our hands on one at CES. Until then, check out the PR after the break.
