I wouldn't say that a phone is superiour regarding that aspect either. Printed matter is as unlimitted: if I run out of material to read, I just buy another book, which there are thousands to be considered just within the subject of Christianity. If I don't use the phone that much, I don't need to carry the charger with me. I live in a somewhat cold climate, if it's really cold the battery of the phone doesn't work well. Books are highly readable when it's really cold as long as You don't drop them in the snow. If I carry a phone and go between very cold damp areas and warm areas, condensation builds up and damages the phone. I've also experienced that palm sweat can quickly and severly damage the phone, the only damage it does to books is to the cover (if it's not covered by plastic foil) and to the edges of the pages.
I don't understand what You mean here by comparing apples and oranges.
I really can't figure out how You mean that would be equivalent! To me, clicking to jump around doesn't give the same feel at all, as does moving Your focus and looking at different printed translations. I can have all the Bibles on the desk, open. To do the same with electronical devices I can't read by moving my focal point but would have to click. Besides, to constantly look at the abrevations of different versions, would also be be tiresome.
