It’s more than just the ability to get in or out of VR — VR has space requirements for most applications; even if you’re standing still, you’ll need space around you for your arms to move. VR, in part, is a real estate problem.
I have a headset I bought a few years ago (PSVR), and while it’s easy enough to set up, I don’t want to rearrange my living room every time I use it.
