Not a single feature that the casual user will be hyped about. All this FaceTime and group sharing is so niche, weird they spent so much time on it
I think its not the most exciting but its definitely not bad
Safari mobile extensions is a massive plus
Notification summary is very useful
Focus has extremely powerful profile customisation, definitely a big plus
Live text is really useful, and it works within safari on images without any extra steps which is awesome.
Ive already found the new photos memories to be great
Private Relay is basically a built in VPN, also a nice addition
Spotlight and Siri both got significantly better
AirPods can be tracked just like airtags! this one is amazing
And then the other stuff like per-app text size & format and other accessibility settings, reordering Home Screen pages, weather, translate and maps got much better, "shared with you", the built in Authenticator with 2fa code autofill, notes & reminders improvements, new widgets etc
Im definitely not disappointed in iOS 15
