People sound like they are over-rating how good interacting with 2d apps with goggles can be. It is "really neat", a really wow experience the first few times but it quickly gets old and things like "scratching your nose" or "drinking coffee" become far more valuable features than anything the goggles can provide.
I think we are in for a frustrating few years where the faithful go absolutely bananas over this because of the Apple brand until people quietly admit that they don't actually like having their peripheral vision filled with fake scenary or app windows or whatever. It's much nicer to see your real cat snoozing on your desk instead.
