I think the relative user experience of the platform might also drive the particular outcomes. For example, I do a lot of my shopping online. From my desktop PC. I have an Android phone. It's garbage. There's no way I could buy something with it even if I wanted to. I have an Android tablet. It's fine, but I don't do much shopping on it. Would I shop more with my mobile devices if they were Apple? Maybe. My coworkers show me their most current generation Apple phones and tablets and WOW it's like I stepped 10 years into the future. I agree that economic issues are a reality, but many low-end Android devices are not useful for shopping or paid apps, so that artificially makes the Android market look worse. It would be nice if the graphs could be further subdivided by some metric into, say, Android 4 devices capable of running apps, and older Android devices that don't have the speed, space, or otherwise are unusable anywhere outside of the phone or text screens.
