As VR becomes more and more mainstream, a key to its success will be the choice of headsets available. On the entry-level end is the HTC Vive, at $99. On the upper end is Valve’s Index, which features two RGB LCDs running at 1,440 x 1,600 pixels, capable of a 120Hz (or 144Hz) refresh rate and selling for a stunning $999. Senior editor Devindra Hardawar reviewed the Index and found that it had nearly every feature one would expect to find on a high-end VR headset, including finger-sensing controllers, excellent image quality and plush cushioning around the eye pieces and rear head strap.
