> I don’t have much reason to use it as a TV

The tech is just way too early. If it was just a pair of glasses today, your TV is still leagues better in resolution and clarity.

There will be a day where VR reaches parity with TVs and allows you to have any size you want in any space/position you want, complete with lighting control and the ability to share the screen with anyone across the planet as if they are sitting next to you - in a small form factor.

When that day comes, the reasons become a lot clearer. Though I think AR/VR will share this virtual display category as there are reasons why having a view of the real world is important at times.
