[EDIT] it also seems to me that good presentation and communication skills are how you achieve "you don't apply for jobs, jobs apply for you" status without top 1% tech skills.
I use PPT for low-level conversations. You can double click on graphs to see the numbers.
I'd love to find a tool that composes more attractive presentation media than does powerpoint. But I'm too blinkered by my and everyone else's use of powerpoint to know what that could be.
1. One of the best communicators I've met strongly suggested never to present from powerpoint on screen, but rather create a brochure to print and hand off to participants. His claim was less that it impresses, but rather that it changes dynamics of "presenter vs audience" and makes it more of a "discussion group / workshop", which tends to be a more productive dynamic, especially in sales/persuasive setting.
2. Alternatively and more prosaically, dear gawd, 99% of people using PowerPoint don't know how to use it. They don't know how the slide show view interacts with a Webex presentation, so they end up sending a small thumbnail to projector, presenter view to remote audience, but hey things look ok on their screen so they keep going. PDF would alleviate some of those issues :P
Plus you don’t have to worry about the errant slide transition working its way in, and it tends to load faster.
I don’t, as a rule, include video or other fancy effects in presentations ( they’re still referred to as “slide decks” where I work ), so PDFs are perfect. YMMV
