The only part where i have a problem is the exclusivity. Apple may own the typewriter but you own the words that you write. I think Apple may have a ground to charge you for using their typewriter somehow, but restricting where you decide to publish your work goes far, very far.
In the end, it's a matter of being in agreement with the contract. I doubt anyone reasonable would accept such terms willingly - an author wants to spread their works as much as possible, and not limit them to a single marketplace.
