Nintendo 3DS arrives with kid warning

-We're all familiar with 3D movies and even 3D TV's, but now 3D handheld gaming devices. -This is the first time it's a glasses-less 3D technology on a device that already has a lot of popularity. -CNET's Senior Editor, Donald Bell, has been reviewing mobile technology for years and says the Nintendo 3DS will raise the bar on what people expect from 3D. -It's definitely living up to the technological promise of the device. The 3DS is packed with new features and among other things, a feature called "Augmented Reality." -So, it looks like this game is playing out on your desk in front of you and it can look like the table is warping. -And then, there's the 3D camera. -I can take a 3D photo, nice, and then send it out to all of my friends with the same device. -It's definitely for a younger audience that can put up with and be excited about the novelty. -But unfortunately, it's not geared for all audiences. Nintendo has made it clear that this device in the 3D mode is not suitable for kids age 6 and younger, sighting possible harm to the eyes, and for older kids, doctors say, "Use caution." -Right now, we don't have data to suggest that it would necessary harm a child. However, having said that, like any activity that adults and children do, moderation is probably a good idea. -Good thing, there are parental controls and a switch where you can turn the 3D capabilities on and off.
