The answer also has a great piece of wisdom in its footnote: > "That's why we prefer to use power point presentations and (maybe even faked) screen shots to present software in early stages of development, instead of really running a live installation of the program." When I was giving speaker training, I was always telling people to avoid live demos. There are many things that can go wrong and ruin your presentation with the main culprit being the WiFi connection at the venue (or lack thereof). Invariably, people would not listen to the recommnedation, to only have their presentation fail miserably exactly for that reason. Even those with no live demos where not immune, since they hosted their presentation online.
