VR is still early but it's convincing. Have you tried a very good VIVE setup? I've only used it once but that's all it took for me to understand that VR is the future of immersive entertainment. Based on that experience it seems apparent to me that the only thing stopping it from becoming mainstream is the clunkiness you describe. However, we should all know that it's only a matter of time before that clunkiness is replaced by a better engineered form factor.
