This Friday, Apple's newest iPhones will go on sale with the latest version of its mobile operating system pre-installed. iOS 9 has been available for existing devices (going back several generations) since last week, but it's already made a big impact.
Apple announced today that between September 16 and 19, over 50% of devices were upgraded to iOS 9, making it the fastest iOS rollout ever. The company's Phil Schiller said that it's "on pace to be downloaded by more users than any other software release in Apple's history."
While iOS 9 took just 72 hours to reach 50% adoption, this stands in stark contrast to the rate at which its largest rivals have rolled out their major OS updates.
Over eleven months after Google first announced Android 5.0 Lollipop, the newest versions of its OS had reached just 21% of active devices. Meanwhile, it's been almost two months since Microsoft began to upgrade PCs to Windows 10, but strangely, the rate at which it's rolling out the update has evidently slowed down.
Whichever way you slice it, Apple's latest rollout is hugely impressive - and not just in comparison to its rivals. After all, it took Apple itself a full year to reach 87% adoption of iOS 8, but at this rate, iOS 9 could catch up with it pretty quickly.
