I've always been an Android guy. Had every Nexus phone and several vanilla Android phones before the Nexus range started.
This year though I have just been so underwhelmed by the Nexus 6. Nobody wants a 6" screen on a phone!
I made the switch to iOS and got myself an iPhone 6 which I'm in love with.
I haven't got time for crappy UI overlays like Touchwiz - too much bloat ware.
Yeah I'm gonna miss wireless charging and the freedom of rooting but Android is too fragmented now. Apple have it right - one branch of devices and accompanying operating system.
