I think that a iTablet must combine both multi touch and stylus, like a combination of a Wacom Cintiq and a iPhone.
I have for many years used a notebook (a physical one) great to jot down some sketches in meetings, some text etc and can also be used as a diary/logbook to remember who I have talked to, what we have decided.
Here is a scenario from my life: I am an Engineer/designer so I like to draw ideas, which will evolve during time, start with a mind map (excellent on a iTablet) or a capture of a whiteboard. Or why not by connecting different iTablets (think bonjour services) into a large virtual sketch board, where we can interact with each others sketches. Then I refine the sketches, add annotations and weblinks. Go to my office, create a CAD model (on my desktop) sync the documents (meeting agenda, requirements, patent documents etc) to my iTablet and then present them at a meeting, easy to interact using the multi touch, zoom in, pan, annotate etc. At the meeting I get a lot of response, which is synced back to my desktop where I can continue to work.
So why not a tablet where I can access all my documents, (I dont mainly createthem on the iTablet), I can browse them with the multi touch like in Leopard cower-flow mode. I can also annotate onto them, and attach audio recordings.
Today several implementations of audio transcription exists that works pretty well, why not going around, speaking to create e-mails by using a Bluetooth headset.
I have seen many new programs such as Google earth, Gogle Maps, Sketchup etc perform very well (much better than with mouse/keyboard) on a multi touch implementation, so we have to redefine the user interface.
Combine the iTablet with a decent camera that can be used as a scanner with OCR capabilities.
So for me the iTablet would be the companion I use in meetings, traveling etc, and back at my office I bring up the traditional desktop with mouse and keyboard.
When I m out doing daytrips I seldom create new material, I revise and interact with documents and presentations already created. Then of course I surf the web, read and create emails, but I dont write long books when I move around and travel. If I go away for more than one day, than I bring my laptop.
