I never stopped to think about that, it’s so true.
I have 16 physical books within arms-reach of me, plus my kindle. And I have the physical books nearby because they are what I go to when I want to quickly and easily look something up, research a topic, reference a phrase/paragraph/concept, or just skim a subject. My kindle, which I use daily, nevertheless takes a back-seat unless I am reading a Dhamma or Buddhist book from cover to cover, or a DN or MN sutta from beginning to end.
My kindle, as much as I appreciate it, is no replacement for my physical Dhamma books. But then again, I am a total book nerd.
