Of the many apps available on iPad release day--and the continuing flood of new additions coming in as developers get their apps primed for the new device--a few key apps came straight from Apple. As reported when the iPad was initially announced, Apple has created iPad versions of its popular iWork productivity suite, including Pages, Numbers, and Keynote apps--each of which is available for $9.99 at the iTunes App Store.

We've had a chance to get a close look at each of the iWork apps and have found them to be extremely useful on the new platform. Obviously, the touch-screen keypad won't be as efficient as a keyboard for serious writing, and the lack of print features require some extra steps, but for most other purposes the iWork apps will be useful to anyone trying to get some work done on their brand-new iPad.

Pages for iPad seemed like the biggest stretch for a touch-screen device like the iPad, but with Apple's keyboard dock stand or a Bluetooth keyboard, it works quite well. Even with the touch-screen keyboard, we were able to type at a fairly fast speed. Find out more about Pages in our review.

Numbers for iPad is Apple's spreadsheet program, and we were pleasantly surprised with how easy it was to interact with the app. Creating spreadsheets and graphs is incredibly easy on the touch-screen interface, and Apple has streamlined the job of using your spreadsheet data through smart interactive tools that tie your information together.

Keynote for iPad lets you make professional-quality presentations using an intuitive interface that just about anyone can master. Everything from slide-to-slide transitions, imported images and movies, to cool-looking animations are all possible with only a few swipes of your finger. Find out more about Keynote in our review.
