I'm staying on the Android front as I prefer the customization options on Android devices, the ability to have widgets etc... and don't want to transfer my apps from device to device.
Sometimes, the equivalent to free Android apps are paid iOS apps! And I'm not paying for an app that is free on Android.
Plus, find me an iOS device with a microSD card slot... and in the future, headphone slot! (I won't buy something that has no headphone jack or microSD slot).
Here's hoping that the LG G4/G5 gets VoLTE, and on unlocked devices!
