Hi Hive account@icedrum,
To clarify we are Vr/Ar content producers. We buy as many output devices as we can to do testing. what i was too short in saying, there are cheaper AR devices to view content with. Occipital Bridge is Apple's AR device mixing MR with it for $900+iphone.
Also you can use HP or Acer MR headset which has Ar based inside out tracking in a VR lens for $500 CDN. Lastly Lenovo has the phab series phones which are 300 or 800CDN but not in marketplace yet.
Windows has made Edge browser HMD able meaning with the right code you can immerse content of the web through webVR...the future is awesome!
This might be a better subject for you to post about as a continuation of your article and explore various AR derivatives.
