That's no different than a library or house burning down. That's not something that is lost because of moving from a paper book to an ebook.
So no, it's not obvious. If you want to take that tact then it's MUCH MUCH easier to backup because of your 'concern'
Yes you need a display of some type to see it, but that's simply a difference, not a loss.
You can't read pbooks in the dark, eh?
