As someone who owns a house (after a long time of having much less space), I can state that you'll never get enough space.. not if you wish to stay married, at least. I just don't have the space for all my books, in this relatively large house. Other things constantly compete for the space. I've had to throw away a lot of books. They're hard to even give for free to used book shops, they get so many books from people like me.

In other words - I wish for unlimited storage. A house, unfortunately, isn't even close. There was a book I read, once, which had a house much larger on the inside than on the outside..

I use a Kindle for a lot of books, one reason is that it's so much easier when traveling. Another reason is that my vision isn't as good as it used to, years before I got the Kindle I changed from paperbacks to the larger variants simply to get the larger font. The Kindle lets me adjust the font to something I can read comfortably in every condition. A physical book is still better in many respects though. It looks much better, it's easier to skip forth and back, and if the book contains maps or drawings (fantasy or tech books), a physical book is tons better.
