So many things wrong in this article but the base most fundamental issue is that iOS is in the position it is because of the app store and the stellar quality of the apps available in it. This is overwhelmingly driven by the XCode and MacOS X development platform. Microsoft showed during the 90's if you want to control a platform win the developer market. Sure lots of developers hated them but they had such a large dedicated group that it drove the adoption of the platform and made it dominate. Apple is in a similar position, not in market share but in revenue and profit certainly. They aggressively invest in their developer community while for the most part google invests very little. Mac's are key component of that strategy.
