Apple's watch has lacked battery, gps, performance, waterproofing, and a consistent UI. At $500 for 2 years of useful life, no appreciation, and a required $500+ iPhone purchase, the cost greatly exceeds the value. The learning curve and lost features of the OS update didn't help.
That said, not having to reach into my pocket when I don't need a big screen has been hugely rewarding. I can't imagine not having a smartwatch anymore. Notifications, messaging, phone calls, sports scores, workout activities, and media control are all possible even when hands are full.
