At one point, Apple’s wearables group was its fastest-growing division, with many hopes and dreams pinned on it. Apple’s famous head designer, Jony Ive, saw the Watch as their gateway to fashion, launching it at Paris Fashion Week and selling a $17,000 pure-gold version. Others inside Apple saw it as key to their future of connected, dispersed computing, envisioning the Watch as the key to an Apple car, an authentication device for all your devices, and a core part of their “spatial computing” virtual reality headsets. The reality, however, is that people use the Apple Watch the same way they’ve used other wearables — as a health tracker. The market has long reached saturation. What was expected to be a high-growth division has become one of Apple’s slowest, which is why the new, revamped Series 10 Apple Watch is so important for the company.
