The biggest difference between an ebook and a paper book? The sound they make when they hit the floor after you fall asleep reading.
@MichaelPryor Thing is, I have a large enough phone to read on so I can take a ginormous library full of books with me with zero added luggage. AND they fit in various electronics without taking up any more space in the room. I still buy my absolute favorites in paper form, in case of the apocalypse or something, but otherwise, ebooks have those beat easily.
