I have re-bought books that I had physical copies of just so I can use Kindle. I now HATE physical books. They are unwieldy, there is no light, and there is no lookup when I want it. Scriptures are fantastic on it, for daily reading (lookup is better on the iPad).There just is no better way to read in bed.

My wife is a real fan of physical books (she has a "library" in the house and her mom is a Librarian), and even she has just started using a Kindle for daily scripture reading and admits it is better. Yeah, it is.
