Their own iPad apps - the iWork suite, iMovie and Garageband are very capable in producing some pretty neat content.
iWork and iMovie are available not just for the iPad but for the iPhone as well. I've found the iPhone version of iMovie to be very competent for casual movie editing - proving that content creation can be form-factor agnostic.

When the iPad came out it was (naively) decried as a device that segmented computing into "content consumption" and "content creation". Apps like this continue to prove that wrong.

In contrast, even MS with a similarly closed ecosystem, provides a development system on Windows Phone with a tool from Microsoft Research that allows users to write, share and run code from the cloud directly on the phone. http://research.microsoft.com/en-us/projects/touchdevelop/
