I've read that LaTeX can be used also for presentations, using specific packages to make slides in PDF.
But I'm wondering: since LaTeX is a typographic language made to separate content from style, and being PDF a format designed for printing; what are these presentation tools meant for? Maybe I'm thinking about the wrong type of presentation?
What's the reason for using LaTeX for this task?
UPDATE: I'm asking this because I'm about to start making a presentation, and yes, I'd prefer avoiding PowerPoint; I like vector graphics and I was wondering if it's possible to create a sort of vector animation, or anyway something of platform-independent. But I find PDF too static for this purpose (maybe it's just a personal feeling).
