How to create Powerpoint presentation on Leopard
I bought iWorks 09 along with my computer, and Keynote does indeed make some spectacular presentations. Just bear in mind though that even though it will save as a Powerpoint readable file, that it will not contain any of the attributes such as animations or slide transitions that you see in Keynote. Any movies will show, but they will launch in Quicktime and not show embedded in the slide as they do in Keynote. It is like comparing ginger ale and Perrier Jouet. As an experiment however, I saved my Keynote presentation as a Quicktime movie and that works perfectly. Everything is maintained, only problem is the file size is still very big. OK if you are planning on burning it to a DVD or showing it on your own computer, but way too big to email unless you are uploading it to a large format site.
I have posted the question re the possibility of reducing the file size of the Quicktime movie on the Movie forum on this site. You might want to keep an eye out and see what kind of response I get.
Keynote is amazing though - really!
