But let's put the price of adoption aside for a moment and assume that at some point it will come down in price. Even then I can't imagine that the average household will be buying this.
For one, you wouldn't want to use an HMD in any context other than sitting alone in a room, and that's something that the nerdy hobbyist market doesn't mind, but to the average person it makes it nothing other than a novel toy. I keep hearing people on CNBC talk about how this year the Superbowl will be able to be watched via an HMD, and how this is the future of media.
Are they serious? Have they ever heard of a Superbowl party? I watch football around friends, and we enjoy good food and beers. It's a social event first, and a content event second. How does an HMD fit into that? It doesn't. And I think most media we have today (save for video games) are social events. I watched the Breaking Bad finale with friends. I watch scary movies with friends. And that's not to say that I don't sometimes watch things alone, but when content creators have to worry about accommodating both of these experiences, it's difficult to make the VR experience comparatively worthwhile. VR content is going to face the same fate as 3D movies do today.
It might be the evolution of video games. But that's a far cry from the hype that it gets.
I think that the evolution of Google Glass is what will really take off.
