Already got it at home
Except in my lovely cheap homebrew system you need a light-glove for any real range and a pair of polarising specs for the 3D. But the point is the functionality is there. And it's really impressive for, say, spinning Google Earth around or showing off if people come round. Maybe rotating static graphs, basic data manipulation.
Unfortunately, it's utterly useless for the 3D visualisation as shown- rotating is a PITA as there's nothing to get a hold of- and because of that there's no real way to make sure you're correctly anchored to the object. Then it doesn't spin at the right rate (though that's probably a limitation of my rig...) and anything more advanced (say, applying a force to a wheel in Pro/E Mechanism) needs either a plugin or some seriously complex gesture controlled command-macro system.
I can see this making it into some films, maybe an episode of Cribs or two. Maybe even that Star Trek Flat guy's next home. But as someone who's used something very similar, I've gotta say it's just a gadget without a load of practical applications. At least until plugins are created to support it.
When they can add in Force Feedback it'll be a far more useable system.
