Flagship android phones are close to flawless not only in hardware but in the integration with Google services, which are far beyond anything Apple has the ability to provide. As a Samsung S7Edge owner I simply cannot relate.
My point is that using Android means to entrust an advertising company with access to every last bit of your personal information.
Trying to limit what they can learn about you is what I compared to training a dog to guard your sausage.
Ultimately it's just that I'm very attuned to my phone, so I want to delay and minimize hassle with it as much as possible. The same reasoning isn't always true of every device I own (I run Linux, hack things, I'm quite used to playing with my devices), but I think this is fairly reasonable. I don't really blame anyone who uses Android and feels the exact same way (by all means, I'm sure it's a perfectly reasonable alternative since the Android 2.0 days of yore, when I first went to iOS).
I might pick up a refurb Nexus as a work/burner phone for traveling though.
Did I mention I don't want to have to re-purchase FFVII again?
