I think it's a purely cultural thing. You're very used to one thing, and thus don't like that other thing.
Imagine the following test:
Take x children, aged 0. Never ever give them a book made from paper, but only ereader devices. Tablets, e-ink readers, any form as long as it's not paper.
Take a second group, also consisting of x children, aged 0. Never give them an ereader device, but only paper books. Hardcovers, soft covers, paperbacks, any form as long as it's not electronic.
Now, once they've turned 18, switch book reading methods. Then, when they're 20, ask them which format they prefer...
"I followed you."
"Because you were moving. It's impossible to follow someone who is standing still. If I hadn't moved, I would have lost you. Thus, follow."
