Apple has announced that iOS 8 adoption has reached 69% as measured by the App Store on January 19th. That's an increase of just 1% from January 5th when Apple last measured the number.
It appears as though adoption levels have slowed down following the 4% jump attributed to holiday sales of Apple devices.
