Keynote speeches at CES are similar to festival concerts with all of the electric gadgets, but without the mosh pit. Each speaker gets very limited rehearsal time and even less tech time. Of course, the goal is to create a show that rivals a "normal" keynote - but with very little time to do it. For Sony, we sent a mobile system to Las Vegas so Warwick could continue to program after tech time was over. He was able to build a show and implement notes from the producer, achieving a successful show.
