Gamers will love this, they will certainly be first to jump on this. I think FB has finally released a good VR headset that can lend itself to a huge variety of applications.  

I can imagine Zillow providing a VR experience where you can virtually walk around a house/condo using this headset. Car dealership Web Sites giving you a virtaul ride on cars.  Travel Web sites doing virtual tours of cities.  Possibilities are endless.

This is the kind of mass application that NOK should have produced, not a 60K camera.
