Every technological leap we take forward is accompanied by the complaints of those stuck who are in the past. But make no mistake when it comes to virtual reality (VR). It's not a fad. And it's only going to get better over time.

But you don't have to take my word for it. Using a $15 Google Cardboard viewer---yes, it's literally made of cardboard---you can have a basic VR experience on the cheap and see for yourself. And despite the limitations of the underlying mobile platform---Cardboard works with both Android handsets and the iPhone---it's still pretty damned impressive.
