Windows MR works with SteamVR now, and with the Samsung Odyssey plus on sale everywhere for 230 bux, people are buying it like crazy.
Its cheaper because you dont need external sensors, but its also not as accurate, but accurate enough for most pc games.
I decided to pick one up at this price, and Its rather good, not perfect, But for a 200 dollar headset, I don't expect it to match my sync gaming monitor.
Right now, Great for watching Blueray 3d movies, 3D 360 Content on many video providers, make sure you have 4k video enabled on the streams (including youtube vr) Its like sitting in a theater, and it has good headphones included.
But still has some of the common issues, god rays, slow blacks (not a problem on higher end vr headsets) MVR works mostly on SteamVR. No screen door, but the lenses do reflect light.
I'd say at a 200 dollar price point, people will jump on. But 1500 bux for a high end headset not counting the high end gpu, thats a road block for people.
I hear flight sims, driving games and watching videos are the sweet spot for these devices.
