> On an unrelated note, I really don't understand, why iOS 9 (actually iOS 7+) is so slow on iPhone 4S. This bothers me a lot, and cynical as I am I suspect that this is on purpose and Apple's way to encourage people to upgrade to a new phone. My wife has a four years old MacBook Pro, which after two years inexplicably started to slow down more and more to the point where the most trivial tasks like opening a menu became a major pain. It is very hard to imagine legitimate reasons for why this should happen, especially since my wife installed a bunch of programs when the computer was new and since then did not change anything.
