I think a huge issue the VR groupies don't think about is the visual disconnection of your environment.
Not in the "you can't tell whats real anymore!" way either. Lets say you want to drink or eat something while you use VR, you can't. You want to text someone or check your phone while in VR, you can't. You'll have to take the headset off, do your shit, and then put the headset back on.
That cements its usage as a neat toy rather than a new step with entertainment. Completely eliminating the ability to multitask will make using it for casual shit a drag. How many people are going to buy a toy that expensive with limited support compared to any other entertainment delivery method?
Augmented Reality seems like the more logical step than a huge visor that disconnects you completely from your own environment.
