A huge impediment to VR uptake is having to go through the process of strapping a brick to one's face.
This isn't quite the "just putting on a pair of glasses" experience, but it's much closer to that than the former.
Honestly I don't know why that's not more common. I've used puck-based ones, they're great - far less heat and mass on your face is a major benefit. They're also usually easier to plan upgrades for, as the two most costly pieces (which do very different things and have very different progress cycles) are separated.
