Keynote is good
I’ve been playing with Keynote to make a presentation. There are a lot of things I don’t really like about using a Mac, but Keynote is not one of them.
It makes really attractive presentations. It’s easy to use. The help actually helps. You can export to multiple formats (Quicktime, Powerpoint, PDF, images, Flash, HTML, iPod).
And, it’s fun to use. I’m going to miss it when I head back to Linux.
