I has a number of faculty who would print "slides" on acetate sheets to display using an overhead projector, they had the same potential for being overloaded.

  It's possible to be a bad lecturer and use acetates. But physical constraints still act against it: they are bulky, you can't easily manage a lecture with 100 acetates, they have a tendency to slide onto the floor and make a jumbled mess, and they also cost money to make and take up physical space to store and move around. While you can still abuse them, these factors limit how far you can take that abuse. PowerPoint knows no bounds. I only used to print diagrams and figures onto acetates, leaving writing for the blackboard/whiteboard/blank acetates. You would use one or two for an entire session. I try to do the same with PowerPoint (well, Beamer), but some organisations increasingly mandate the whole thing be word for word on slides and stored in Blackboard for students to get. I find this wholly detrimental to the purpose of giving and attending a lecture, since it constrains the lecturer to this terrible presentation style.
