Apple has announced that its iOS 8 operating system for iPhone, iPod Touch, and iPad now is installed on 60 percent of devices as of November 24. With the latest numbers, iOS 7 is installed on 35 percent of devices while prior iOS versions are on 5 percent of devices.
At its October event, Apple compared its adoption rate of its latest mobile OS to Android's, noting that iOS 8 was installed on 48 percent of devices in just 26 days compared to Android's adoption rate of KitKat, which was present on about a quarter of devices; the difference was that it took Android nearly a whole year to get to the 25 percent mark.
