I haven't seen this mentioned in the comments here: I think this is huge for CAD/CAE. I can see this disrupting current [Digital Mockup](http://en.wikipedia.org/wiki/Digital_mockup) offerings.

Everything from design, analyses, testing moves into the VR environment. Already CAD/CFD/CAE computational models are saving huge costs to companies. Throw in VR and we are that much closer to a tangible, collaborative environment. Very very excited!
