Lols at some of the comments here
I have implemented them in a previous role and I plan to do so again.
What I find amusing is organisations that have spent big money on a VC system, with the touch panel, the cables poking out of the middle; the extra microphone & speakers; the mini rack of stuff you need to run it - and then at the other end or the room, or behind the dropdown screen, is the Whiteboard and there are the attendees taking photos and trying to figure out how to use both at once.
I like some of the features of Googles, but the scope is more limited and you cannot present the screen and the room at the same time.
Version 1 comes with 84" (which is apparently no longer being produced), so if I have two ot three side by side, I wonder how using them as a whiteboard will work?
