I tried Oculus only once, the first one that was sold world-wide, I believe. It was cool, but that was basically it for me. My main concern with it has always been the fact that it requires putting a device on my head for non-significant amount of time and I'm not sure about its health effects. Anybody know any research or studies that were done to this end?
