Hello, Have iPad 2 Mini here still with its stock iOS 10. I don't want to upgrade to iOS 11 due to performance concerns because I heard that iOS 11 is more taxing than iOS 10 however I am worrying I will miss upgrades train and will stay on iOS 10 forever. Should I be concerned? Should I upgrade to iOS 11 and if yes, then is current version stable and not as taxing as other previous iOS 11 versions? Thanks for advice.
