Ebooks are easier to carry.
You can use one to take your entire library on vacation instead of just a few books.
Some of them have lights built in for reading in dark environments.
They're much easier to use one-handed than most paper books.
Some of them are waterproof and will survive being dropped in the bathtub better than a paper book.
You can change the font and text size to suit your preferences.
You can instantly download a new book when you want to read it instead of waiting for it to arrive in the mail or going to a bookstore or library.
They are not "simply inferior" as you put it, even if you happen to prefer paper books.
