I ran into a guy who had Keynote on the MUNI last week and had a brief glimpse of it. He just ran through the basics, but it seemed pretty simple. In particular, I was dismayed by the lack of shapes compared to PP. I use these for diagrams all the time because they look better in PP than imported graphics. Perhaps that won't be a problem in Keynote.
If you have the app, what are your impressions?
