I bet a big part of the topic of this video being so trivial is that there is no real problem that this product solves outside the realm of useless meetings. I like how the video is an unintended (is it?) critique of meetings in general.
As Jason Fried and David Heinemeier Hansson put it(1): "The goal is to avoid meetings. Every minute you avoid spending in a meeting is a minute you can get real work done instead."
Maybe the goal of Enso is to save on travel costs/time?
We use Appear.in and HighFive along with some of the usual suspects (Hangouts, Skype, Facetime) with some degree of success. Not sure when I'd consider this.
