They were in San Fran, at a tech meeting and the internet was going on and off. It didnt work right to start, then needed reboot, then live feed went dead LOL.
The best solution would have had the video of the other demos resident on the phone/tablet for those occasions (the video itself, not a link to youtube etc). That way as long as the projection mechanism was working you could pop up something.
But it was a good night, and I think the presentation got a few more views on the stock as volume was up and it held steady...
Everything I post is my own opinion and people should always do their own research and due diligence on any company they are looking at
