So, what exactly does the web traffic market share has to do with anything? Sure, iPhone is popular in US, Canada and Australia. A lot of teenagers have it here and they consume a lot of web traffic (youtube, facebook etc.) Teenagers in other countries who own mostly Android phones are a little bit more busy working for a living and have less time to waste on messaging to their friends about what they had for breakfast.
It goes back to the notion that Android phones are replacing feature phones... and being used as such.
I guess you could say that Android phones have huge market share... but Apple phones are used for more things.
It's just an interesting data point.
And you kinda glossed over the rest of my earlier comment: "developers overall are more happy with iOS... and iPhone customers are extremely satisfied."
