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.
