To be usable or not, it is a question of interface. It could memorize a sequence of zooms/rotations. Ej for a two column text the zoom could process to "repaginate" the book so that each page is shown in four pages. As for panning, moving, etc, you can use the keys instead of the pen.

PDF is a page-layout format - not an eBook format. Zooming does not work like HTML where the text only gets larger. Zooming a PDF makes the whole page larger.
Now, if the PDF was formatted so that the actual content was in an area roughly the proportions of the iLiad screen, then zoom becomes useful: you zoom in until the text fills the screen - probably making it easy to read.
However, if the content is formatted to use the whole (larger than the iLiad screen) page, then zooming is sort of like reading a book through a microscope - you can only see part of the page and have to pan to see the rest.
(And I won't get into how using the pen reduces your battery life.)
I don't know about the rest of you, but I'd rather read a pBook than an eBook that I have to pan around to see all the content - making zoom and pan a useless feature right now.
Now, supposedly tagged PDFs will work as they should, but I haven't gotten around to trying them out yet. But I don't have high hopes.
