From the OP:
> ComScore's data suggests though that comparatively few iPhone owners actually take the trouble to use Google's maps rather than Apple's - in part because Apple's maps are the default for any driving directions or map-related search on iOS 6 and above.
Obviously, Apple advocates would argue that this is a victory based on technical implementation...Apple Maps may not be the greatest, but the consistency of UI and behavior, in the long run, is better for users, so say the Apple advocates.
I use both an iPad and an Android...I'll likely never go back to an iPhone because the Google implementation of things is so much better...it's not just maps, but the keyboard...it's unbelievable how much better Swiftkey is than the iPad keyboard...I can hardly type on the iPad without making typos due to autocorrect, on SwiftKey, I can barely deliberately make typos.
And of course, iPhone users scoff at the idea of "having" to install a keyboard. And I'll give them some credit...the way that Android keeps asking me what I want to do with a link when I click it from an app (such as Twitter) can be annoying, because I'm the type of person who won't pick "keep this as default"...I say sincerely that it is a cognitive benefit when iOS just makes the choice for you. And I'm saying that as a technically-proficient person...for those who aren't, this lack of choice is probably an overall benefit to their happiness.
