I love my Oculus, at least for my use case, exercise, and I highly recommend it. I think exercise is the killer feature of VR, personally.
For context: I'm not much of a gamer. But I was looking for some way to do cardio exercise in my small-ish apartment. I heard from a few people about exercising in VR. so I got the Oculus.
And it's been great! There are lots of games that are purely exercise-focused, which I liked a bit. Then there are lots of games which are just games, but that you also can get a workout doing, which I absolutely love. There are enough of them that I think I can keep playing for a while before ever getting bored.
I love table tennis, but don't regularly go play anymore cause kids/family/etc, lack of time. But I can put on the headset and be playing an almost completely realistic game of ping pong with an AI or a random important anytime I want, for a quick 5 minute break or for something more.
Then there are the other games - games that are actual games. I'm most surprised by this - since I'm not a gamer, I wouldn't have thought I would be drawn to these. But apparently games in VR are just much more fun, or at least much more novel to me - and I've actually found myself using VR to play games without an exercise focus more and more.
So to summarize - if you want a way to do some cardio at home, in a relatively small space, without feeling like you're working out - a VR is a great way to do that. And let's face it, most people need to do more cardio.
(I'm also very excited for using VR as a workspace, but way more skeptical of this really being a thing.)
Edit: Oh, and this is way more out there - but if there is ever a good, affordable omni-directional treadmill thing ala Ready Player One - it will instantly make VR 100x more valuable for exercise, and I think it will be completely transformative.
