My sister has a Quest 2, which at least seems to eliminate some of the setup headache and the need for an expensive PC and all the cables, albeit at the cost of some visual fidelity, but she still doesn't use it very much. And personally I will never buy another VR system from Facebook.
But I agree with the "not buying the Facebook one" part.
I considering getting a Quest 2 this year, as the price is a lot lower that what my friends setup would have cost, but after looking at a few "Top VR games" videos on YouTube I decided it wasn't for me. The videos were full of FPS and fighting games, which I can understand in VR would be a completely different experience and fun if you enjoy that, but that really isn't my thing. If more casual games come out then I could see it becoming more mainstream, but right now it does seem a bit of a fad.
Aside: The relatively low friction involved in starting game play has me playing this far more than I ever did with my rarely used X-box One. It remains to be seen whether this lasts beyond winter here in the northeast US.
It's not really about the improvements in technology, rather than the inherent limits in its use cases - there's only so many games and media experiences that truly benefit from VR, and as a rule, they're designed for VR from the beginning.
Without a doubt, VR is a huge leap and a drastically different and exciting medium, but that doesn't mean it's ever going to be more than gimmick worth a couple evenings' entertainment to most people.
