Ok, but that is a pile of assumptions. If the iPhone user buys 3 apps for every 1 the Android user does, but in a couple years there are 10 times as many Android users, where do you sell your app? The attach rate and the market size make all the difference, and there is no data to support the conclusion you are trying to make. A gaming PC is a hell of a lot more expensive than a console, yet their attach rate is way way lower than a console.
