I am impressed, the technology is developed far enough that you can lose yourself into the virtual worlds. But that is also a problem, as I'd rather not "lose myself" by disconnecting from reality too often.
The experience isn't casual enough because you need to make time and physical space and then check out of your first reality.
There is a popular game called BeatSaber which is an innovative demonstration of what VR can do and a way to burn time, but it's by no means a killer app that warrants the start up expense.
More interesting from a utility perspective is app called VRChat that puts you inside a virtual house, or lounge, or a club or something and you can talk to other people's avatars as if you are sharing the same room. This could be really interesting for long term relationships and socializing (for example, to play chess together), but I can see why nobody would fire this up when you could zoom call.
I have doubts as well that this tech can ever be more than a medium sized niche.
