Apple does not appear to have an editorial board, nor do they have a specific market or markets under which they will sell your book, or discernible standards by which your submission will be measured. Doubleday has editorial and marketing staff that will work to make your book as polished and marketable as it can be. Doubleday has sales reps and distribution channels and foreign rights managers that will get your paper book into as wide a range of bookstores and other retail outlets as possible.
Apple actively restricts your retail outlets to one. And, when your contract term with Doubleday runs out and your book goes out of print, you receive the rights back and you CAN trot down to Delacorte and see if they want it.
