That's subjective. I'd say that Android phone with a weather widget is much easier to use to get weather forecast than iPhone. What evidence do you have that iPhone is easier to use?As far as I can tell, the iPhone does the following much, much better:
*Ease of use
*Simple integration
This is achieved by limiting OS feature set. Then again some examples would help.
*Availability of accessories
True but the appeal is limited. On the other hand, while Android ecosystem offers fewer accessories it does offer way more phones. iOS - one phone model. Android - dozens of phone models. I'd say this is more important than limited selection of accessories.
*Quality of apps
Only anecdotal evidence. One could argue that some apps (like Maps and Navigation) are much better on Android. The major apps released by large companies are usually identical on both platforms. Besides, even if Android is still lacking in app quality it offers more types of apps (Apple does not allow many app types into App Store)
*Frequency of software updates
What about it? Android had two major updates (ICS and Jelly Bean) since iOS 5 and iOS had none. In just this year Android got major UI update (and reached iOS smoothness level) and Voice Interface update (Google Now) that gave Android better capabilities than what Siri offers.
