Agreed, as a kludge. But exporting images of known sizes means even in power point you get like sized (ie scaled) images, located in the same place on the slide, etc. Print Screen is more likely to result in views that jump around on the slide, and/or require crop management in PhotoShop. An extra step that a properly thought through and executed tool doesn't need.
And I would guess we are about 15% power point, 85% presentation boards. And moving away from power point when possible. When talking to a community meeting, users group, school board, etc. boards have a warmth and a certain quality about them that power point just doesn't have.
And the simple fact is, Autodesk should know better than to ship eye candy that won't print.
