1) One of our server goes down. 2) My watch tells me about it. 3) I can decide a) Reboot it b) Replace it c) Send a callout to my Ops team.
All in less than 10 seconds ... used to take 10 minutes, including taking out my laptop, checking what's going on, finding out who's on call.
We have a few dozen of these.
If it's possible with an Apple Watch, surely you could also do it on your iPhone?
That's the problem with the watch for me - not that it can't do things, but that those things are also possible on an iPhone, and the extra expense/remembering to charge/etc isn't worth it for the ~3 second convenience.
1. Server goes down
2. Smartphone tells you about it
3. You can decide
3-a. Reboot
3-b. Replace
3-c. Call ops team
Conclusion: Same same, and you still need the smartphone to use the watch. So not really that interesting.
