Pages document from my Mac to my iPad

The desktop/Mac OS X versions of the iWork apps have not been updated to take advantage of iCloud yet. In the meantime you can go to iCloud.com, sign in & click the iWork icon where you can upload & download files. You could also try e-mail or Dropbox. Hopefully we will see those updates, maybe even a whole new version of iWork, soon.

I would imagine the update will happen sooner rather than later, but then, I expected it to happen by now. But it does seem the iWork engineers/programmers are far removed from the rest of the Apple teams & move at their own, very slow, pace.
