VR is not just for high-end HMDs; it's also for the big wide mainstream web. Oculus and Facebook are pushing towards that future with Web VR: the React VR platform and "Carmel" browser.
It's worth pointing out that the WebVR protocol (W3C proposed spec for all browsers) that the Carmel browser will use is already in development builds of Google Chrome, Mozilla Firefox, and (soon) Microsoft Edge. Individuals and brands have been creating Web-based VR for almost 2 years, and there's a library that lets older (mobile) browsers simulate WebVR. So, you don't have to wait for Oculus, you can begin working with WebVR right now! It will be interesting to see exactly what Oculus does with their own browser.
