IOS vs Android

This is incredibly misleading. Saying that the difference between iOS 4 and iOS 7 is equivalent to the difference between Android 4.1 and Android 4.4 is absurd.

The big jump in Android was from Android 2 to Android 4 (Android 3 was mostly a release for tablets). Sure, there are differences between Android point releases, but they're not as substantial as the "major versions" the chart suggests.

Is this a joke ? Should we really take this seriously ? Specially, because this is being reported by a Magazine from a country that iPhone runs Android ?
