Just because you are not used to using am iPad for davening doesnt mean its any differnt.
When printed siddurs first came out I am sure most people had to get used to them, I am sure most had hardly ever even seen a Book.
It will take a few years, but people will get used to e-books and people will see how much better it can be.
Artscroll is making a Shas for iPads and other seforim will follow.
