Of course, likd Android, this conference too has gone truly global. We are very excited about the 5000 plus people that are in this room. But this year for the first time we did something new. We created viewing parties. We allow our developers to set up their own viewing parties and stream this event alive. And we have over 110 cities have these viewing parties set up. In the screen behind me any moment we can get the sampling of what's going on around the world live right now. We have viewing parties in nearly 132 cities including places like Cairo where we have over 1000 people. It's 2 a.m. in the morning in Cairo. And so... To the more than 10,000 people of the viewing parties and many many thousand who are watching on the Youtube, welcome to our conference. We are truly humbled by this worldwide enthusiasm. We do recognize that you are sharing with us your most precious resource--your time. And so we hope the next two days are incredible valuable, exciting and a lot of fun for all of you. So let's get this show started and to do that, I'd like to introduce the Hugo Barra--director of Android product management to kick off the opening keynote. Hugo.
