The only feature I’m really missing are Safari content blockers. In case you were wondering, the requirement for this feature is an iOS device with 64-bit processor, which means iPhone 5S or newer, iPad Air or newer, iPad mini 2 or newer, and the 6th-gen iPod touch. As I observed on social networks, slightly older devices would benefit a lot from content blockers, as there are certain sites with so many ads and underlying related code that browsing them is an exercise in frustration and a blow to the device’s general performance. Too bad (and ironic) that they can’t take advantage of this iOS 9 feature.
