More than 50% of active iOS devices running iOS 9

Caitlin McGarry, writing for Macworld:

iOS 9 has been out for less than a week, and even though some reported problems installing the upgrade right out of the gate, Apple says more than 50 percent of devices have already adopted the latest version of iOS.

That means iOS 9 is on track to become Apple’s most popular software upgrade of all time. Apple announced the adoption rate in a Monday press release about iPhone 6s and 6s Plus availability, which is also expected to break records. The phones will go on sale at 8 a.m. local time this Friday.

This is worrisome, especially after the distressing news last week. If Apple maintains this insane momentum, how do they ever expect to not spiral into irrelevance?
