Haven't used Keynote, but looking into using it for some (hopefully) VERY simple animations, maybe exporting to iDVD (based on what a book describes).

Has anyone done this? Results satisfactory? Any comments welcome.

Content would illustrate a book I'm preparing on guitar fretboard layout & reading. Animations might be something like dots or letters, brackets (lines), added to a fretboard diagram. - Still a work in progress.
