I just thought some other features that I want to suggest to a device like this:

1. "Importance" list. Similar to bookmarking, when user reads the book/document, and he finds a page to be important, he can mark this page as important. And when he is in the book, he can invoke a list from menu to see what pages are important, and can quickly jump to there by clicking the item on the importance list. For a device as large as this, it will be nice to also allow user to input the reason for importance, and rate the importance, so the user will have more information to be displayed at the importance list, instead of just numbers of pages to jump to. (And importance list should also work with handwritten notebook too).

2. "Book binding". Occasionally, user may find pages from different books/documents to be useful for a single purpose, so he might want to put those pages together into one place, so he can access them collectively, smoothly and quickly. So a nice feature would be to have a program on the device called "book binder", and in book binder, people can create "custom book projects". When user is reading a document/book, he can insert pages into a specific book project. And when he wants to reproduce the book, he can open the book binder, access the specific book project, and invoke book producing, which will produce a document/book (probaly pdf) that holds all the pages that the user has so far inserted into (it should also allow the user to organize the order of pages inserted). Also it should also let user to insert pages from his hand written notebook pages. An extension of this feature can be also let user to insert html pages from web, to capture what he reads from online that is important.

In concerning to copyrights issues, a copy right protected document (DRM protected, or other sorts of digitally protected) or book (brought from online store) may be prevented from inserting pages to be reproduced in custom book, or to have a limit of x pages (10 pages etc.) to be able to insert.

An alternative way of dealing with copyright that is to give the user an option produce a "virtual book" (which allows user to produce virtual custom book that holds copyright content). Each page of the virtural book is simply a shortcut to the original page in the real document, and user cannot view a virtual page without having a correct document at a correct directory location.

That's all I can think for now.
