All valid points QD. Especially the cost. I'm not bothered about multitasking myself. Ask the GTA crew members, we usually grab breaks between sessions so that aint a factor for me. VR headsets take not much longer to put on than a pair of headphones btw. The whole point in VR is that it's full immersion, so it's meant to cacoon you and take you away.
There will always be TV gaming too. Just like there's still 2D retro style platform games. But VR is the future imo.
