With the exception of the time, you need to use a voice command for everything else (as far as I can tell)... so i'm not sure being less disruptive is the primary use case.
It's not, that's my point. OP was saying this is revolutionary because it's less obtrusive then checking your phone and I'm saying it's equally or more obtrusive.
I think its less obtrusive for the user, as they don't have to look down or can pretty much use it within their same field of vision vs a phone or watch. In terms of being obtrusive to a person that you're conversing with, thats subjective. I wouldn't care, but others may.
