Take a look at Keynote on the iPad. You can build presentations with text, images, charts, shapes and transitions. You can present them on your iPad's screen, using an external projector or monitor, or export them as PDFs for printing.

You should have at least mentioned in passing that the iPad version is NOT compatible with the Mac version of Keynote. It loses font info, rearranges the text and is generally unusable. I don't know if the reverse is true, though.
Apple SHOULD have made them compatible. It's far more natural to design your presentation on your Mac and then put it on the iPad to show. I hope they fix this soon.
