If you look at sales the ratio of Android devices in poor countries is significantly higher than the US. But, for the vast majority of US developers it's pointless to count those people.

If you look at actual US sales, both iOS and Android are on the rise mostly by eating BlackBerry's lunch. Android is still almost 2x the size of iOS but again there far more popular on the cheap handset market and are harder to target due to the fragmented market.

And of course, looking toward the market saturation point, every survey I've seen shows that the Android-> iOS switch rate is significantly higher than the iOS -> Android switch rate. If that changes, Apple should watch out.

Another interesting statistic, from Opera, was their report that iPad produced more ad revenue than all of Android.

Maybe because a far superior mobile browser, Chrome, is available on Android devices?

I use Chrome on my iPad.

Chrome on iOS isn't quite superior though. It's got a nicer interface but it feels much slower.
