Apple's answer to PowerPoint is a slick, drag-and-drop-easy iOS (and Mac) app for creating visually compelling presentations. The app includes 12 presentation theme templates to get you started. You can also import and edit PowerPoint decks and export back to PowerPoint or PDF. (To start, you may want to email the PowerPoint deck to yourself and open it in Keynote, or open it from your Dropbox folder if you have the iOS Dropbox app.) Apple's Keynote Remote app ($1) lets you use an iPhone as a remote control for a Keynote presentation on your iPad over a Wi-Fi or Bluetooth connection. You can control a Keynote deck on a Mac as well, but only over Wi-Fi. The app also displays your presenter’s notes.
