Sunday evening saw the final CES keynote delivered by Bill Gates in his current role with the Microsoft corporation. Speculation about big announcements generally seemed to be for naught, as his last address at the show focused more on broad concepts than blockbuster news. "Gates outlined three major themes for the second digital decade-high definition displays with 3D experiences and high quality video and audio, connected services and the power of natural interfaces. Gates had a vision early of those themes, but his quest to make the Tablet PC, Media Center PCs and natural interfaces, such as speech and touch, more mainstream has not been realized." A full description of the talk, including his Guitar Hero finale with Slash, is available in Engadget's liveblog of the event.
