Two things:

• iOS 9 hit an adoption rate of 61%
• iOS 8 or newer hit an adoption rate of 91%

Hitting 61% this quickly is remarkable. Passing 90% for the last two major iOS releases shows the lack of fragmentation in the market and the real value in Steve Jobs’ original vision of controlling the hardware and the software.

The splintering of hardware control in the Android universe amongst a variety of manufacturers means low/slow adoption rates for new Android releases and, ultimately, makes it very difficult to build a cohesive defense against malware.
