Same here, but I don't think the ecosystem/market is ready for serious work, it's all too brittle and the UX isn't nearly there yet. So I'm waiting.

But I do own a HP Reverb G2, mainly for playing simulation games like flight simulators, and racing simulators. Once you get used to having a spatial understanding of the environment because of virtual reality, it's near impossible to go back to using traditional monitors against. The immersion is 100x better and your skill increases as well, just with a VR headset (in the genres I play).
But outside of simulation gaming, I have 0 use cases for VR, it's basically a fun toy at this time. But I think probably in the future there will be more use cases, but remains to be seen.
