Wow. great to see so much engagement with my post! Unfortunately it was a typo. I meant live demos ON my phone. I showed voice search, knowledge cards, google now, chromecast and glass. And all the tech worked for once.
I was lucky enough to be there and thought it was a fabulous presentation. At one point I leant over and said to a colleague "If that were me on that stage, I would have forgotten to switch on my phone GPS or something" Dan and his prep people did a great job to avoid techy hitches. (The glasses looked strangely fetching on you Dan)
