My Apple Watch is my most loved tech device. It's to the point that even if I'm using my Samsung phone I still wear the Apple Watch.
It's a 64GB MP3 player on my wrist. Can download Spotify tracks and run them off the watch without the phone. Can be used as a Spotify remote and control music on my Samsung phone.
It manages all my workouts and syncs either to my health apps or syncs to the Apple Health app that my apps get data from (I use Withings, Hevy, LoseIt, and Nike Run Club)
It monitors my health and gives me feedback
It manages my timers
When I have my Samsung phone on me which has a different number I just turn on call forwarding and use my hotspot and it's pretty much like I have access to my iPhone even though it's at home. I get all my calls and text and don't have to pay for mobile data on the Apple Watch (cost $10 while a second line cost me $15 so obviously I opted for the 2nd line).
Apple got their hooks into me with this device. I'll probably never leave. I do have to turn off the Always on Display and Hey Siri to get over a day's battery life on a single charge.
