[new] even with only the daily minor mishap... (none / 0) (#1)

Almost every highly technical talk I've seen has had some error in some equation somewhere. When the talk is on the blackboard or transparencies, the correction can be made on the spot. On powerpoint or other laptop presentations, the speakers always just say there is an error.

That aside, I don't think laptop presentations have any advantage over transparencies unless there is some animation. Calling up data and graphics tends to be slower than pulling out a transparency and powerpoint could've been printed out anyway.

Furthermore, transparency presentations are rarely as clear as blackboard presentations in analysis and differential geometry. The speaker can only really interact with the audience using the blackboard. If the speaker is forced to write out the equations then the audience has time to absorb them. Only when there is some nice graphics or data to present is there an advantage to using the overhead.
