It doesn't come with a stylus, but that doesn't mean that they don't exist.

There you go. Now you just need to find the best app to use to take notes and do your diagrams.
As far as multitasking? It exists for Apple apps which I would assume would include the iWork suite.
So yes, you should be able to launch a song on the iPod app, move into Pages, start typing, switch to Safari, research and copy/paste what you need and move back into pages without missing a beat.
They need to extend this to 3rd party apps, and I'm sure it's coming soon.
