Just took delivery a day early of a new gadget and have to say that it is pretty awesome.
hardware feels good, solid and not 'plasticky feeling'.
Just had a play with one of the inbuilt 3d games ' face raiders' and was blown away: here's the setup:
First you ou take a 3D photo of your own head, then the DS creates an animated version and starts to blast it around the room (the screen acts as a camera viewer with the heads flying around your current location in 3D). You aim at the moving heads and blast them out of the sky, the heads laugh at you and try and kiss you. You miss a shot and it takes a virtual chunk out of your room- as you move the camera the removed chunk stays in place - how cool is that!
This is not your Dad's Nintendo DS ... instead of seeing kids quietly sitting intently staring into their DSi's you can now expect to see those same kids waving their 3DS's wildly around as they blast their virtual enemies.
