Go figure - Apple making lots of profit on watchbands!

I enjoyed seeing this article by Julia Love @byJuliaLove of Reuters, in Business Insider this morning. In addition to having sold 2.79 million watches, according to Slice Intelligence @SliceIntel, apparently Apple is selling, and making lots of profit from, the watchbands that go with them. It's the oldest business model in the books, or nearly so - the classic "razors and blades" model that I first remember learning about in college days, when a friend worked in a camera shop and was trained to never let a customer leave the store without a case and other accessories, after buying a camera body. Interesting that I remember the market leader of the day was the Canon AE-1.
