> 9. render the presentation as a pdf file, so any device can display it

That's good as a backup, or for simpler presentations (in a good way!) but Powerpoint allows you all kinds of benefits like animations or transitions. Presnting PDFs is not guaranteed to be pain free as well, as I expereince on my corporate controlled laptop with stange versions of Adobe software.

It does! also remember that the audience doesn't know what you are going to present, so they wouldn't care if you make mistakes.

I will add

Those are not benefits. Do not do those things. Anything more complicated than embedding a video is a distraction and will not help your presentation. (And the video can be done by alt-tab to VLC or linking YouTube or ... .)

Seriously, trust me on this one.

I have seen a lot of presentations in my day, from sales engineers trying to sell me on things to literally hundreds of guest speakers from all over the world back when I was in grad school. That last one was especially valuable, because I got exposed to a huge variety of speakers and styles, not just a monoculture from one place or company.

And the best of them either never used that crap, or it passed through my brain leaving so little evidence of its existence that it may well never have been there to begin with. I only remember the bad associated with that stuff: a speaker once had to answer a question, went back a couple of slides (fine so far), then had to wait fifteen seconds or so for his dumb, contentless transitions to play out, each slide he advanced, trying to get back to the slide he wanted to be on. Stuff like that is all that's in my head when I think of transitions and animations. The best speakers really do just never bother with it in the first place.

I know. I just go for very basic stuff - large fonts, black text on white background, no border, no colors. I ruthlessly eliminate everything but the point I'm trying to make.
