"The number of people worldwide switching from cell phones to smartphones in the coming years was going to be so enormous that he [Rubin then at Google] just needed to focus on that group -- not necessarily on iPhone customers -- to get a dominant smartphone market share. It seemed unfathomable that Jobs would lose two battles the same way a generation apart."
I recognize that Google/Android/Rubin has had a high degree of commitment to the handsets-sold metric right from the beginning. But I also know that I've seen a whole lot of people buy Droid phones, tablets, etc. including things like the Fire. And a non-trivial number of those people bought a later device over on the iOS side of things, when they realized that they were really frustrated by all the apps that weren't available on Droid (yet) -- or not on their device, anyway.
I don't expect things to stay this way forever, and it's just possible that someday, iOS will be a has been, backwater app universe and smartphone choice. But it's almost 2014, and iOS owners are still spending a lot more money buying apps, and within apps, than Droid owners. Which presumably counts for _something_.
