But it's comparing web usage for iOS vs. web usage for Android. So in a direct comparison, it shows that iOS is more usable than Android by examining one specific capability for both systems. It is logically extended that other capabilities (apps, music, etc.) are utilized at a similar rate. It is unlikely that iPad users spend all of their time on the device browsing Safari, while Android users eschew browsers completely and only use apps.
We'll just have to disagree.
I also think iOS is more usable to the average person, based on using both current OS versions. However, the web metric only shows that iOS devices spend more time surfing pages. It
implies that the browser experience is better, but it might just mean that the types who buy iOS devices are more inclined to surf, and the types who buy Android devices are less so.
More likely, it's due to the fact that most Android devices are running ancient versions of the OS. With the Nexus 10, you're looking at the state-of-the-art Android OS. This points to a major weakness of Android - the fractured landscape - but it doesn't point to a weakness with Jelly Bean 4.x and the Nexus 10. If most iOS users were on iOS 2 or iOS 4, there'd be similar issues.
Further, while I also personally agree that iOS apps tend to be better, the web surfing metrics absolutely do not prove that other apps are better.

I think you are able to get refunds on the appstore, almost sure i saw posts from people regarding that subject.
If so, I think it's must be new, per-developer, or via effort. On Play, you just click to get a refund, and after 15 minutes, the option goes away.
If it's readily available in iOS 6, I've missed it and will look for it.
