I had it.  Returned it for the Reverb G2.  The G2 is better in both clarity and colors--I run it on a 3090 GPU and top of the line CPU, with plenty of RAM.  I could not justify the cost of the Index.  Plenty of new other stuff out there and, in the near future, I will upgrade.  I am holding out for the "perfect" unit that will have the biggest FOV and the best resolution.  I think that the future is good for VR.
