Remember, you can always take the PDF documents I post electronically here on my (other teacher's) site(s), and import them into DocAS (on your iPad), or any other PDF converter that allows you to type on / annotate/ or edit rather than write.
And...as you know (sometimes better than I), you can also always use a doc scanner app to scan any document (or just take a good picture), and then use DocAs/your favorite PDF editing app to type as well.
