Page numbers will never be fixed on e-readers since you can change the font size which thus alters the number of pages the book has.
The Kindle gives a location range for each page, and those locations go to specific places regardless of font size so you could cite those I suppose. Though none of the style guides currently have that--probably because different e-readers use different systems.
Now iBooks does do page numbers, but when you change the font you get different number of pages, so just citing a page number wouldn't work since it doesn't correspond to a specific paragraph etc. like the Kindle location numbers. Guess for that type of system you'd have to cite page number and font size or something.
But yeah, that's something that needs improved and standardized across devices and e-book formats so they can develop a citation system. I just stick with paper books currently for all my work related reading since I have to cite properly.
Listing the paper book page number is another pretty good solution IMO, I didn't know the Nook format did that.
