I find it amusing how they advertised this: "HD OLED screens generating a virtual 750 inch screen from 65 feet away"
Can't we be more honest in how we advertise these things? Who knows what 750 inches looks like at 65 feet away?
After converting them both to meters, it's 1m screen at 1m away, +-, which means less than 90 degrees Field Of View horizontally. Oculus Rift has, if I remember right, 120 degrees horizontal FOV and 90 degrees vertical.
