(I'm already tempted to buy another Sport band and the Milanese.) Annual upgraders. Yup, yet another Apple device for customers to upgrade to. Encourages users to upgrade their iPhones as well.

The amount of profit that will be brought in from this new category exceeds the margins of the rest of the company's lineup and will help push Apple towards being a trillion-dollar company.
