Not hearing a lot of love for this thing so far... I pretty sure the 144hz mode is a game changer that no other HMD can boast. Waiting for reviews as always before pre-ordering.
VR headsets already "Strobe" the back-light (LCD) or OLED typically at 90 Hz, so the motion quality is already very high. 144 Hz will give small gains. Resolution though is where large gains are always realized and unfortunately the Index falls short in that area.
