This is beyond disgusting. How did the people in the room not simply walk out?

ETA: Scripts are good for these things. It's difficult, in the shock and confusion of the moment, to decide what to do. So, here's one script. When you're in a presentation, and a speaker starts talking like this (or talking about "gang-bang interviews" or whatever else) you stand quietly, and you leave. You tweet what happened. If there isn't a clear apology (and we haven't heard one from Dell yet) you don't attend the conference the following year. This is how we, as a community, communicate to one another what kind of behavior is and is not acceptable.
