Of course "I" don't need it. But you see, there’s this kid of mine. In his school, you’re somehow pushed to use PowerPoint (see Microsoft schools programme)... So he’s confronted with his friends who totally abuse the visuals (and the teacher somehow likes that too). So social pressure comes in. And although the kid could use LibreOffice, he’s so dissappointed to not be able to play in the same league as his friend that I have hard times convincing him to stay out of MSFT. So no, I don’t need animated transitions but he does (and don’t start me on the fact I could explain him why transitions are a distraction, usually).
