i still have not decided if I should upgrade to iOS 10 in day 1. I have tried iOS 10 Public Beta. While I can see the performance is OK, but I never really liked the new way to unlock, I dislike the new notification system. It is like crappy clone of Android's lock screen notification, but done worse. The big white buble is just ugly. Anyway, who will update in day 1 and who will wait and see?
