I just finished a book that I started with a physical copy but switched over to my kindle and finished it there because it is much easier to carry around, also with the Kindle app on my phone I can read the book when I have a minute or two free during day (and I'm not on CB).
I still prefer paper scriptures though and refuse to give them up, though I do use the electronic scriptures all the time and have added a bunch of cross-references and outside info to.
