Looks nice, but cost may be a problem. At Google in 2013, there seemed to be one conference or small meeting room for every 7 or 8 people (I am guessing about these numbers, but hopefully close). Their meeting rooms had relatively low cost monitors that ran Google Groups. Shared Google Documents took the place of the collaborative surface on a Hub. I was in Mountain View and my team mates were in NYC so I used these meeting rooms for an hour or two a day. Pretty effective. As another guess, the Hub might increase the cost for each meeting room by $10K.
A cheaper alternative might be really good screen sharing and group drawing access for Microsoft Surfaces. That might even be preferable as far as getting stuff done.
I thought about cost first as well, and I imagine this isn't targeted at people who are picking Google Apps for cost reasons. I figured like most Microsoft products, this is focused on the Enterprise, and they'd be much happier selling 100+ at a discount than one or two to small or medium firms.
We have these fancy Cisco video conferencing systems in all of our conference rooms with MASSIVE TVs instead of projectors. I imagine they're at least 10k.
The best part? They don't even work. The HDMI inputs never work and we always have to us VGA. The sound doesn't work at all. We brought in $20 Logitech speakers just to play a video.
If the Surface Hub even sort of works it'll be worth it to most big companies.
