I mean, i'm not going to buy it... but only because I think the vive offers a better experience. I think VR in general is pretty promising, and a bit more than "niche"
We're talking $1500 for the headset and GPU able to support the headset. Plus a pretty beefy workstation to feed that GPU. Plus the games don't actually exist yet, and they face a massive chicken-and-egg problem. No one but the most dedicated early adopters will buy this until the price comes down like 3x.
