That's not Pages' main strength. Sync with other devices isn't fully operational yet. Pages is a good word processor but there may be better options for note-taking. Check out Evernote and the like for note syncing.
A texteditor is the best for taking notes on any device.
The iPad is IMHO extremely clumsy for typing.
I have its predecessor, the Pen and Pad. When I discovered that I was simply amazed. So quick, so easy and no glitches except when I run out of ink or paper!
