http://www.nma.tv/ Nintendo recently released the 3DS, the world's first 3D portable gaming device. The technology is revolutionary and illustrates just how far the handheld industry has come. However, British newspaper The Sun claimed the 3DS "left thousands with dizziness and headaches." The tabloid also said buyers were returning the devices en masse, which turned out to be untrue. Some safety concerns do remain, though. Nintendo has stated children under 7 should not play games in 3D mode. But as any parent can tell you, monitoring kids' behavior isn't the easiest of tasks.
