Around minute 25 there appears to be a very awkward waiting-for-the-Steve-Jobs-applause moment after Elon explains the updated navigation system. A few more announcements are made without applause and then finally, just before the 31 minute mark, applause is finally handed out when the launch date of the Model X is announced. I hope Elon didn't feel disappointed with himself or the audience. Applause is cheap. The questions that followed demonstrated audience buy-in more than any amount of applause could ever achieve.
