For me, it comes down to price. Put simply, iPhones are too expensive. I'm already invested in the Apple ecosystem with an iMac (albeit from 2008), two iPads and an Apple TV but I cannot justify dropping over a grand for an iPhone 8. And forget buying yesterday's tech like the iPhone SE for over AUD $500. That's pretty much my argument for deciding to go with Android. However, one thing I am worried about is the comparatively weak security of Android over iOS, W10M and even WP8.1. Sure, Google pushes out monthly security updates, but that's dependent on the hardware manufacturer. Also Google guarantees a mere two years of updates from whereas Apple's commitment lasts far longer.
