I have an OG Vive, Oculus Quest, and a Cosmos with the wireless adapter. Several hundred hours of SteamVR over the course of the past few years. All that said, I can do 1-2 hours of VR every other day or so at most. The idea that this will be as popular as smartphones in the next 5, even 10 years seems crazy to me. Being "in VR" is pretty exhausting no matter how lightweight the headset is.
