If you want to share your work with someone close by, you can also use Airdrop to drag and drop presentations to them. Integration with iCloud has been vastly improved so that you can start working on your presentation on Mac and finish it on iOS at a later stage. It is amazingly easy to create presentations with Keynote on Mac and the application walks you through most of the process and does much of the hard work for you via a collection of Apple presentation themes and templates. Integration with iOS has also been vastly improved in this latest release, giving you the ability to import and export PowerPoint and Keynote for iOS slides and themes. While business presentations can easily be spiced up with Keynote, with photo presentations you only have to drag and drop photos and Keynote does the rest. In this latest version, there are new transitions including Shimmer and Sparkle and the ability to add reflections to shapes. Adding and removing backgrounds is simply a drag and drop process, while there are some gorgeous themes to choose from which make your presentations look slick before you've even got started.
You can add transitions and effects into KeyNote that are simply not possible with PowerPoint, including moving objects and animations.
