You're totally right. My mom absolutely loves her phone and yearly, iterative upgrades are godsend to her. And that's why i think Apple went into other devices to please gadget-loving crowd, such as watch or headphones. I think that would explain decline in sales. Stage has been set and the movement is rather small between the platforms.
