I'd have to agree with others that this article does a poor job of giving any insight into the numbers - and is wrong about Android being ahead in 8 key countries - it's actually 6 of the 8. This Guardian article at least gives a bit more breakdown of percentages but still doesn't give the total numbers:
http://www.guardian.co.uk/technology/2011/jul/11/ios-android-blackberry-smartphone-data. Is the report itself available or do you have to pay to access it? Haven't been able to turn it up in a quick Google search.
As a fan of the iOS platform myself, these numbers are nonetheless worrying as it shows a huge swing in favour of Android over this quarter last year. However, 2 things:
-it is only quarterly sample data, so can be heavily influenced by short term trends, and the iPhone 4 is an old model now (the Verizon boost only affects America and that is one of the few countries shown where Apple increased their % share over the same quarter last year). Even then it shows that Apple need to improve their refresh rate though.
-Along with this there's the fact that Apple still has twice the installed base of Android in the UK (the only market for which I saw total figures given as well as quarterly). That makes the headline of Android being the most popular OS a little misleading for me when it's based on such short term numbers. But then I am a begrudger :-)
Nitpick: I wish they'd stop labelling it as "iOS market share" and then only count the iPhone. Either call it iPhone market share or else include all iOS devices.
