I upgraded all three of these operating systems the day they were released:
- iOS 10 and watchOS 3: 3 September 2016
- MacOS Sierra: 20 September 2016 (yesterday)
Didn’t really care about Sierra, but I was bored and I wanted to upgrade to that before getting and starting to use OS X Server on the Mac Mini at home. I put Sierra on my MacBook Pro and my Mac Mini yesterday. Then I put OS X Server on the Mini.
I really enjoy iOS 10 and watchOS 3 seems like a really good upgrade.
