Brave New Phone Call
That's an awful lot of hype that sounds like it was written by (or for) someone who has never used Skype, or Hangouts, or , all of which do store-and-forward messaging for individuals and groups, and let you call people with a touch of button.  Hangouts also shows me if someone's on mobile or desktop, and whether they're "present" or not, and while it doesn't tell me exactly where they are, that's arguably more a feature than a bug.  Same goes for apparently recording everything forever (cue image of legal departments around the world reaching for the NOPE button).What am I missing?
