If the pitch is for a great product that people want to use, does it really matter if it's on a Mac or Windows laptop? Substance is more important than style.

If the pitch is for a great product that people want to use, does it really matter if it's on a Mac or Windows laptop? Substance is more important than style. I use PowerPoint, but I design my decks using the principle of "austere minimalism". Each slide makes one point with the minimal amount of material. Keynote wasn't better or worse as a presentation tool when I had a Mac.
