If your new computer came without PowerPoint software, or you are bored with the same old and want to try something new, here are a few free options:
1. Google Drive: All you need is a Google Account to create presentations and more. Download your presentations or store them in your Drive account. You can access your presentations on your iPad with the Google Drive app.
2. Slide Rocket: Create and share presentations. Basic version is free. Show your presentations on your iPad with the SlideRocket Player app.
3. Prezi: Instead of advancing from one slide to the next, Prezi features a whiteboard method for presenting ideas. You can store and show your presentations online or download to a device, and show your presentations on your iPad with the Prezi app.
