Ars Technica: "At E3, Nintendo mercilessly mocked the idea of wearing glasses to experience 3D. The company's newest handheld, the 3DS, gives you a brilliant 3D effect without requiring expensive or annoying glasses, and Nintendo seemed happy to point out that advantage. It didn't help that the gathered press and bloggers left Nintendo's event to go straight to Sony's press conference... where we were handed 3D glasses upon entrance. Ouch.
Sony has responded to Nintendo's dismissive tone, and the company seems oddly hurt by the attacks."
