In late 2010, I did a survey in my office with my co-workers. 9 of them had Android devices and only 2 of us had iPhones. I went door to door and asked everyone if they had ever purchased an app for money. Only Android user said yes, but it took him a while to remember what he had even purchased since he didn't use the app anymore. Both of us who had iPhones purchased multiple products including on Cydia (The jailbroken app store). We both also made purchases early on when the App Store prices were still in the $5 - $10 range for apps which are today mostly free. This seems to be a continuation of that trend; More total Android devices with less total revenue.
