> Smartphones are broad and universal, whereas consoles are deep and narrow, and deep and narrow is a smaller market. VR is even deeper and even narrower, and so if we can’t work out a form of content that isn’t also deep and narrow. People are now playing those console games on their iPhone. The average paying iOS user spends $9.60 per month on in app purchases. The game market is huge, bigger than movies & tv combined. Maybe in the current form VR & AR is niche but that says nothing about how valuable the market can become. The lesson is you shouldn't predict potential market size of a technology from the first particular hardware implementation.
