What is your favorite program out of iWork?

Tweet

My favorite and most used program would have to be Keynote only because I find myself using it the most to type. It is much easier and feature-packed once you learn your way around the program. I also like Keynote, but miss the Clipart and Wordart from Powerpoint. They are probably somewhere but I just don't know about it. I haven't even opened Numbers. What is your favorite program out of iWork and why?
