What to read what on

I read a lot of fiction on my Kindle. It was a present from my kids last Christmas - my son's suggestion. He canvassed opinion: will she hate it, someone as bookish as she is? Yes, they all said. So off he went and bought it anyway - 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 because you can't flip back and forth as you might wish to, consulting a map or a plate; and you can't make references for academic purposes because it doesn't show page numbers. Or at least I think you can't. If someone knows how to please tell me.
