Powerpoint
The thing about presentations is that they almost invariably make your brain want to doze off... Unless you've just had, say, a venti mocha with an extra shot to try to prevent that exact situation, and the darkened room and monotone of the presenter aren't enough to put you out. So you actually pay attention to it, or try to. Of course, after the first 30 seconds or so of each slide, there isn't any new information for your brain to absorb, no matter how hard the presenter tries to repeat the same thing in different ways. That's when you start trying to remember when was the last time you saw that particular background, and getting annoyed by the corny "appear from top" effect for the bullet points... I mean, please... doesn't everybody know that the "fade in" effect looks much more professional? And you should use the same effect through to the last slide... and at the end there is yet another meeting, so of course, another day working OT just...
