Sulon isn't discussing pricing for the Q just yet, but it should be available in late spring. Whether or not it works as well as promised is another matter. How well it works will depend on the software you can use with it. And while the Q is pitched as "lightweight," strapping a computer to your head is likely to be more burdensome than wearing a focused device like the HTC Vive or Oculus Rift. If Sulon pulls this off, though, it'll be much easier to understand for VR newcomers who may not relish the thought of buying an expensive PC (or connecting to any device) just to get started.
