When you try to turn a page that doesn't exist, it is not completely unintuitive that it doesn't turn the page... Turning the last page in a pbook doesn't close the book, it merely leaves me scratching futilely at the inner side of the back cover flap.

It is of course intuitive to press the home button when you are done an ebook, much analogous to closing a pbook.

Perhaps I am just used to the Kindle's way of doing it, but I cannot see why turning the last page should close the book.

I rarely turn the last page meaning to leave the book, generally it is because I don't realize there are no more pages. With a pbook is much easier to spot this.

Of course, the Kindle is not ideal in this regard either -- it opens a popup asking you to rate the book, even if it is a sideloaded PDOC.
Fortunately, this is not often an issue for me in any regard, as I can usually tell from the About the Author page that I have finished reading and there is no more content.
(I did have to setup a system where the EndActions get removed, so it wouldn't pop up earlier as well.)
