Less Than a Month After Release, iOS 7 Found on 71{813a954d5e225a1509f22204ece89c855080ce25555f20805f61bed63cbfde3b} of iDevices

iOS 7 was considerably different than the versions of Apple’s mobile OS that came before it, and the days following the announcement were filled with complaints from adopters who wanted to revert to good ol’ iOS 6. As it turns out, however, a new report from Mixpanel (via 9to5 Mac) suggests those iPhone users are in a small minority.

By how much? Consider this: Just 27 days after it went live (by October 14), iOS 7 has been installed on 71 percent of all iPhones, iPads, and iPod touch devices. In the words of 9to5 Mac, that means iOS 7 “could be the fastest spreading iOS update to date.”

Compare that to the adoption of iOS 6, which had “only” reached 61 percent of all iOS devices after 30 days. That widespread adoption likely had much to do with the significant changes Apple made to the latest iOS, with redesigned core apps, a Control Center, and new visual effects only scratching the surface of the new features. If Mixpanels’ numbers add up properly, that means that roughly 250 million iDevices were running iOS 7 as of last Monday.

But nothing about the data is so interesting as how it compares to devices running rival operating systems. As revealed by data from NetMarketshare (via Fortune), Google’s Android “Jelly Bean” operating system still only calls 48.6 percent of Android devices home, and Windows 7 (if you’ll allow us to jump to desktops) still hasn’t made its way to 50 percent of PCs over four years after its release.
