Microsoft PowerPoint 2013 has a brand-new look: It’s cleaner and primed for use on tablets and phones, so you can swipe and tap your way through presentations. Presenter View automatically adapts to your projection set-up, and you can even use it on a single monitor. Themes now come with variations, which make it simpler to hone in on the look you want. And when you’re working with others, you can add comments to ask questions and get feedback.
