I don't really mind the one I prefer to read among the two, but due to the challenges that comes with reading of soft copy books, I often going for hard copy. Challenges of soft copy are the straining of one's eyes on the screen as well as the consumption of battery life when reading it on devices. As for the effect, the brightness of the screen have on my eyes, I usually feel its damaging them. This is the main reason I don't like the soft copy of books.
On the other hand, I like my hard copy book, because it is convenient for me to read. Additionally, I like the smell it provides when I flip through the pages of the book I am reading. And being able have it held on my hands makes me feel some sense of closeness to it, which in turn raises my passion and reading time span for it.
