It's the most impressive VR device I've ever tried, but it's still not enough. A singular, enclosed, isolating space that you can really only wear for a few hours at a time (eye strain and fatigue) just isn't a mass-market product. It doesn't have to be, but it's definitely not the next "big thing" like the iPod and iPhone were in their day. As a niche product? Sure. But it's one hell of niche they've got.
