I believe there's no "right choice". Is whatever suits you and makes you feel comfortable. In the last 5 years I have move 6 times! even two of those I moved to a different country, so there was no chance for me to keep physical books when trying to put my life and in the smaller number of boxes.

That's the reason I love my Kindle, but that doesn't mean I don't appreciate a physical book. Is simply right for me.

Plus, I don't like to own books. Once, a girl that I was dating with had a copy of Harry Potter that she wasn't able to sell to a library because "it wasn't valuable on its own". We sat down in a cafe, she wrote a little note and left the book in the table when we left. "It will be better with someone that can read it that stored forever in my room", she said
