The gamechanger with Qube is "presence". When you're meeting with someone, everyone else can see who you're with and optionally put a "watch" on you to get notified when you're free again. And the other person gets notified that you want to talk to them.
Conference rooms act just like you would expect... You double-click and Zoom pops up immediately, just like you were walking through a door.
It's crazy how much of a difference it makes for us. It was down for a few hours last year and we all felt lost without it.
