Tony Chor has a good post on “Backstage at MIX06.” The effort that goes into a good presentation, including the practice, the extra machines, the people to keep them in sync, etc, is really impressive:
Normally, when I do a presentation and demo, both the demos and the presentation are on the same machine. I advance the slides and do the demo myself. Sometimes, for a big talk like my keynote at Hack-in-the-Box, we separate out the slides and demo onto separate machines (especially when the demos have pre-release bits like Windows Vista or IE7) and maybe I’ll have someone help me with the demos/slides to keep things running more smoothly.
Well, MIX took that to a whole new level. First, the demo machine was backstage, connected to a monitor, keyboard, and mouse via a switch. We also had a backup demo machine hooked up.
