I was quite surprised to learn that Apple have not quite fully integrated iCloud into Numbers, Keynote and Pages. Surprised and disappointed.
It seems that in the iOS environment the workflow is pretty well streamlined: you work on one iDevice and it is synced with the other via iCloud. It's not so simple when you also want to work on it on your Mac! That involves downloading the file from iCloud manually, working, then re-uploading. Not quite a seamless workflow.
I'm hoping that Apple addresses this soon.
