I had a watch of the promo video and it looks like a very polished bit of kit, but none of the use cases seem that mind blowing to me. Almost all of them basically boil down to it seeming like you have a big screen in front of you, which frankly will never be a replacement for actually having a big screen. Also, no matter how ergonomically the headset is designed it will never be able to escape the social weirdness of having something strapped to your face. I am of the opinion that VR will always be a niche gizmo, it just can never have mass adoption, and I don’t think this will change that. It seems very Google Glass-y to me.
