Late to the party, but the first thing that comes to my mind is an LTE radio. Yeah, there’s the Garmin 945LTE, but that is probably the worst Garmin purchase I’ve made ($12/month, can’t reply to texts, and it will burn through battery faster than an Apple Watch if it can’t find a cell tower).
Why?

This oversimplifies the issue. The Apple Watch has a much broader range of functionality than Garmin's products, doesn't it?
