I like opening PowerPoint documents with Keynote, it is much faster than with Mac Office. But I hate the thing that it always ask me if I want to save changes when I close Keynote. And most of the times I only open them to see the presentation, I don't make changes. But since it isn't saved in my hard drive as a keynote document (only as a .ppt) it always asks me if I want to save changes. And strangely, this does not happens when I open Word documents with Pages. In Pages if I close the app it won't ask me if I want to save the changes. Did I explained myself??
