3 Is a Crowd
It's nearly impossible to demonstrate the new Nintendo 3DS capabilities without physically holding one, so Nintendo are using clever TV ads to give you third-person experience of the hand held machine.
I tried one today and had a little outer body experience, not due to the 3D (which is awesome), but I was able to see myself going 'No way!' like those idiots from the ads. Noam on the other hand didn't enjoy it so much, her experience was, well, closer to the other side of the spectrum.
Lately I've been using Noam's regular DS, which is good enough for me. 2D IS a company.
