Among the uses we are most familiar with was digital storytelling. The post also mentions using iMovie to create visual reports, book reports/trailers, and use it to provide students with out-of-class trips (like an in-class field trip).
While I mentioned previously that I didn't use iMovie, I'm sure I could use PhotoStory to do any of the above-mentioned activities too.
Just some food for thought.
Below is a video narrated by a student explaining how to use iMovie.
