OLPC XO -- it's all rainbows, hugging, and laser beams of learning, right? Maybe not, kind reader. Apparently, users of the diminutive, educationally themed laptop are experiencing a rash of "stuck key" issues which are causing tons of headaches (and possibly some heartbreak as well). It seems that keys are becoming stuck in activated positions, and / or are being triggered by key presses nearby. The company is aware of the problem, but can't pinpoint a single cause, as the components are made by a variety of manufacturers. For now OLPC is asking customers to RMA the laptops so they can get the repairs they so desperately need, though we're not sure how this is going to play out in the developing areas where the XOs are being rolled out. Well, they can probably just take them to the hospital.
