Admittedly, it's hard for me to imagine not being into reading. It's just part of who I am and I regularly read around 100 books per year.
But I've never really had a strong attachment to the book as an object. Unless it's a favorite that I read over and over, I'm fine with not having a bunch of dust-collecting books all over my house. So I jumped onto ereaders early enough for people to ask me about my weird device when I read in public.
I had a Kindle before I had a smartphone.
