Coming from a person who was a PowerPoint fanatic, Keynote is miles ahead.
Keynote IS what presentation compilation should be. Intuitive, quick and easy, with fully customisable animations, backgrounds, text sizes, colours and styles... it's a presenters dream come true. And, all on iPad! It was so easy to create that I could hardly believe it.
Any presenter, teacher or student creating a presentation, lesson, speech or report... this App is for you. My son put his part of the presentation together HIMSELF on his iPad and passed it over using DropBox. I only needed to adjust a few words (for spelling, he was only 8 at the time), and the job was done. Not only that, but he was empowered because HE created the part of the presentation he was to give - not me!
Fantastic, brilliant, classy, easy. Keynote rocks!
