Tim Cook says it’s because iOS has 97 percent overall satisfaction rating amongst customers. For the sake of comparison, 89 percent of iOS users are already running iOS 7. And Android has got only a 9 percent adoption rate for its latest version that is Android KitKat.
It means that Android customers aren’t getting the latest features, and security remains a big concern for Android devices. That is why Cook says that the company couldn’t be happier with the momentum of iOS.
And iOS 8 is continuing that momentum.
A full round of features will be brought to you shortly.
