Just ran their SteamVR benchmark and passed nicely. Really would love one, but I'll be waiting until the 2nd generation comes out. Really love the Vive's external camera though. Apparently you can use it to give you a sort of holographic overlay in-game of the room around you so you don't run into a wall, get motion-sick, etc.
What I *really* want is to get one to bring to work and use a gigantic virtual monitor.
Also would have trouble justifying $800, so perhaps the next generation is a little more reasonable. I'd like to think Gear VR would be worth it, but I just can't imagine the fidelity would be even close to what I'd want.
