This evening I have acquired a new App for the iPad. It is called Note Taker HD, and it is designed to enable you to use the iPad as a notebook, but with lots more features than an ordinary paper notebook in that you can organise your documents into folders, email them, and so on.
It is a great App for just 2.99, but my only challenge at the moment is being able to write legibly on the screen using a stylus. I know that bad workmen blame their tools, but I think that I might have to try out some other styluses (styli?) to see if that helps!
