Got to love people who go out of their way to post graphs and charts and figures with various numbers to TELL people what is "better".
In my opinion, iOS is a far better OS, performance and UI wise, than Android with it's various skins and basic underlying architecture. A person will decide what is best depending on what they prefer, not what a flowchart, piechart, bar chart, or other Excel generated number sheet says.
Oh. And being in the UK, I've used the SII a lot thanks to a friend in work getting one (after Carphone Warehouse talked him out of the iPhone 4 he went in for ... weak minded fool, robbed by an Android commission based sales team). I don't like it, it's too damn big and it feels "plasticy" and flimsy compared to the iPhone 4. And then there's Android.
