All of the built-in apps on iPad were designed from the ground up to take advantage of the large Multi-Touch screen and advanced capabilities of iPad. And they work in any orientation. So you can do things with these apps that you can’t do on any other device.
The iWork productivity applications — Keynote, Pages, and Numbers — have been completely redesigned for iPad. So you can create great-looking presentations, documents, and spreadsheets. You can even share them as Microsoft Office files with any Mac or PC user. All using just your fingers.
