Valve Index review: High-powered VR at a high-end price

I have a Vive and might go for the Index at some point down the line when I have a better PC, and there was one thing about this article that annoyed me (otherwise great though). I see lighthouses as possibly the best way to do spatial tracking, and have had much better success with them than visual tracking.

Basically, they completely avoid the visual tracking problem that can have issues in plain environments, dark rooms, and when the controllers are out of view. They're definitely expensive and I'll be keeping my v1 lighthouses from my Vive for a while, but I think they're worth it for the better VR experience.
