Two major positives I’ve noticed in terms of system animations. I updated a family member’s Air 1 to iOS 11 some time ago - this is the first version where pulling down notifications doesn’t exhibit any lag, nor does swiping to open Control Center. Very smooth now. Can’t speak to anything else though.Still on 10.3 is it worth an update ... or will I regret it ? Anyone done it and does it sort the performance issues with 11.x.
Cheers
