Totally. But today, the room will not be well set up for it, markers may be dry, whiteboard covered in old, settled in diagrams, etc. And half the people dialing in. All solvable, but not in 30 minutes.

And for larger work presentations the expectation even 30 years ago was not whiteboards; that is very inefficient. It was transparencies. But try printing those in a pinch. And finding a projector.

That's not to say that a key tool outage should kill a presentation (and if it was important, do it early); but it is not a do-not-care either.
