Yeah, the DK1 I tried was leftover from some research project and ended up at the local maker space for a while. I assume the tracking quality on that is about on par with Google Cardboard.
I don’t have a space for a real “room scale” setup with Rift cameras or Vive beacons, so I’ve been waiting on Santa Cruz’s inside-out tracking to look at VR more seriously.
Pleasantly surprised by price. They’ve confirmed it’s based on a Snapdragon 835, which isn’t a top end SoC, and I think that’s a smart move to get it down to this range. At $500 they’d have a much harder sell, and this is where PS4 and Xbox One started (once they dropped Kinekt, anyway).
