Android is too Wild West for me. Too much distance between the hardware and how the hardware manufacturers choose to implement the software. It's the same issue with PC's for me. I want something that works more like an appliance since the device and the software it's running is a means to an end for me. An ecosystem of hardware and software designed together works better for me than picking from an array of random hardware/software combinations.
I've used android systems before, they never felt designed together to me... plus I use Mac for work and play so buying into the ecosystem is the most convenient/least hassle... i can't even imagine what it would take to make me switch as each of the last several phones have performed well and done what they needed to do, which in the end is all that matters... I don't feel an urge to explore other brands/platforms that also do the same things my iPhone does... I'm not chasing specs or who has the most Ram or who has the best camera by a small margin...
So it would take a truly compelling reason to switch, and that would have to come from the android side to sway me to their platform and all the hassle that would entail in doing so (media, music, backup, syncing, UX, peripherals, cables, etc) it would have to be an outstanding reason to go through all that effort to undo the ecosystem I have for a brand new ecosystem that I now at the outset is not going to work as efficiently with the rest of my devices, or require a humongous amount of effort and change management on my part to learn new ways of doing the same things.
