Clearly some people prefer iOS and others Android. But that's not the issue, is it?
It wouldn't be hard to come up with a list of dozens of features that you can customize on Android that you can't on iOS. If you really think you're covered "pretty much all the reasons" to choose Android, you haven't researched the platform very thoroughly.
Leaving out stuff like water proof-ness, wireless charging, and multi-windows. These are features which in five years we'll all take for granted. These are real innovations.
I was honestly expecting more from Apple. Apple has the engineers and the component budget to reach the forefront and push it forward. Yet I'm left wondering what their component budget actually went into and where their engineering time went.
Android's famous "fragmentation" allows for this.
In this regard iOS8 begins to close off some of the more significant constraints iPhones and iPads have. For any given individual it may not go far enough but what's being introduced will almost certainly make it a better option for some people and some of those people may now buy iPhones instead of high end Android.
The point isn't that this brings the two platforms level, it's that iOS now competes for a small piece of the market where it previously didn't.
