The weird thing is that with the Rift S and the Index being expensive but debatably a minor upgrade to what I already own in terms of features, the freedom of the Quest and the inside-out positional tracking does make a good case for it being the next headset I get if I do end up getting a new one soon. Of course it would depend on the software, but allowing you to be unteathered does open up the possibilities for arena tracking and new types of experiences. Having owned a GearVR, I know that wireless and inside-out tracking it a bigger deal than PCVR enthusiasts usually would like to admit, but mobile VR has been limited by tracking and performance. Quest does address some of these problems so it does seem like Oculus was right in going this direction in terms of pushing adoption, while other hardware manufacturers can continue to push the technology in other ways.
I still don't think I'll jump in just yet, and the Index does peak my interest just a bit more in terms of features, but cost in VR is still an issue. I'll probably end up waiting until whatever ends up being the next generational leap.
