3d has it's place.
Of course not everyone is going to wear stuff like this for everyday TV watching and yes, the tech has been around for a while. But that's hardly the point is it? This technology works fantastically well on Imax (to Daniel B-T: Have you seen the cyberworld tech demo?)
And at some point soon, in a similar way to the 'Wii', someone is going to introduce a 'killer ap' on this type of hardware and suddenly we will all be eager to look like prats wearing the goggles. But nobody is suggesting a television *replacement* here.
That Elza stuff was really poorly implemented it's true, but think of the possibilities for gaming with even a subtle 3D engine. Some will vomit, others will become more fully immersed.
