Many folks in the K-12 realm are probably aware that you can set up a Powerpoint presentation to act as an interactive Jeopardy (or other type) game. Some examples and templates are here.
A few weeks ago a staff member asked me how to make a collage in Photoshop. I explained that rather than deal with all the layers and their attributes in Photoshop, you can create a photo collage in minutes with Powerpoint. Resizing and setting transparency are a snap.
For training purposes I often include screenshots of programs so that learners will know exactly where they should be navigating. If I drop the screenshot into Powerpoint, it only takes me a moment or two to add arrows and text boxes.
