I've converted many of my lectures from Powerpoint to Keynote. This has been very time consuming. Keynote has really cool slide transitions and graphics capabilities. Plus in my mind the menu makes more sense. However, this is the first version of keynote, and it does not contain the ability to make hyperlinks. This is a major flaw in my opinion. Occasionally I would hyperlink to websites, but mostly I would hyperlink to various documents in the powerpoint lecture. I would even have urim and thummim icons on questions pages that I could click and the computer would randomly select a slide with one of the student's pictures, and they would answer. I can't do that with keynote. But keynote does integrate with quicktime better.
