Yes, I have Keynote, too. I like it a lot. And I managed to procure a converter thingy so I can if I want, or not if I don't. I think I might, if only because it helps to keep me organized.

I have a really good article somewhere which is about how Powerpoint is Evil. Seeing as I am, after all, a tech education specialist, I ought to be able to do Powerpoint (or Mac equivalent) that isn't Evil :)
