I have always been an avid reader - but for some reason only books that I owned. Libraries didn't work for me. And I never threw away a book. So in my houses always a seizable room was reserved as a private library and book storage.
Five years ago I weaned myself away from the paper book. Then I sought (and found) om internet the ebook equivalents and gave away the paper copies. So within a few years I had an empty room here my library once existed. When I moved into a new house, it could be smaller - and cheaper - than earlier houses. I can read in bed without my wife complaining about the light staying on.
Yes, as far as I am concerned, the ereader is the best thing since sliced bread. BTW: I am 69 and it is nice to be able to adjust stuff like fonts and fontsize.
