What to read what on

I read a lot of fiction on my Kindle. Everyone thought that someone as bookish as I am would hate it. It was a gift from my kids after my son had asked around to canvass opinion: will she hate it? Yes she will, they all said. So he bought it. And I love it. And now he wants one too.

But there is a but. I think it's not so good for non-fiction, or for anything where you might want to flick back and forth, turn to a map or a plate in another part of the book and then back to the text. And of course you don't get the page numbers, so if you were wanting to make academic reference to anything - well, you can't. If you can, someone please tell me how.
