LAS VEGAS — If you’re trying to get inexpensive computing devices to those in need, you (theoretically) couldn’t go wrong with making that device a tablet. So thinks non-profit “One Laptop Per Child,” an organization that strives to deliver rugged, cost-effective computers to children in developing nations. The group has jumped into the tablet space with a prototype tablet, on display at CES Unveiled Sunday.

[bug id=”ces2012″]OLPC’s XO 3.0 tablet is encased in lime green plastic like its laptop counterpart. It has a solar panel cover that can generate four watts of power (which delivers two hours of usage) after charging for an hour. It can also be powered using a hand-cranked power supply. Six minutes of cranking will net you two watts of power, or one hour of usage.

The prototype XO 3.0, which has a 1024×768 Pixel Qi display, uses Marvell’s PXA618 ARM-based system-on-a-chip as well as Marvell’s Avastar Wi-Fi tech. It runs either Android OS or OLPC’s Sugar desktop OS, which is based on Linux.

The price for OLPC’s tablet hasn’t officially been announced, but rumors peg it at $100 or less.
