Especially Keynote. Not possibly for most busy executive types to learn any formatting at all in that suite — just not worth their time. Looks amazing when done right. Even without custom graphics. Finding effective stock/licensed photos also not plausible for most execs.

I worked at a 35 person company once where a designer did nothing but Keynote formatting for client decks. Well worth the price. In Menlo Park, no less. Crazy that more freelancers don’t do this.
