I’ve dabbled in VR for decades. Fantastic concepts, very immersive & engaging. It will need a “killer app”, affordable pricing, and market penetration - all coming together soon. Google’s “cardboard” project is a great step, using what people already have; pity developers seem behind the curve.
My idea of a “killer” VR app would be one tied to a treadmill and which let me self guide through the Louvre and other great museums of the world/.
