Ditto for the Quest. I have a Vive Pro and a traditional gaming rig, and I'm very happy with it, but I can't deny that my friend's Quest is by far the more convenient setup. Even discounting the lack of power, the ability to just pick it up, put it on, confirm the play space and go makes the thing infinitely more attractive. Even the low battery life isn't a major concern, since I rarely want to spend that long in VR anyway.

I don't think tethered PC-based VR is going away, simply because that setup is most flexible for development and experimental purposes, but for the mass market, I think a device like the Quest is the only thing with potential to truly take off. Especially if the weight of the headset can be reduced, as comfort remains one of the most nagging negatives of the whole experience.
