I agree with this being a user and a VR dev myself. A couple of things that make the experience somewhat tedious is that you can't really get comfortable if you are on a sofa and then decide to lay down and turn side-to-side. Which you can just watching a movie or playing a game casually using a TV etc.

  Another reason personally also, it is more tedious to develop games for VR wearing and taking off the HMD all the time. I can imagine this would deter other developers not wanting to make VR games, it's already a slow painstaking process to make games already.
 
  I think also the amount of apps you have to switch on your desktop if using PC also means you keep taking the HMD on and off before you begin to play. Too many barriers to entry when it should be a convenience thing, wear and go!
 
 Not everybody is physically fit/young/healthy or wants to just do physical gaming which i think leads to lack on incentive to use VR too. I personally play most games now via my monitor or projector screen and use VR for simracing as there really is no comparisson here. So VR Great for sim cockpit type games, flying and racing but for everything else, it's back to good old pancake mode monitor instead.
