To be fair, you can't just pick up an iPhone and it works the way you want, you have to go through all the settings, and there are a ton.
You could use an Android phone just like an iPhone if you wanted, big grid of icons with no widgets.
Unfortunately for Apple no matter how much they improve iOS, the thing that's going to push my wife from iOS to Android is iTunes. She hates iTunes with a passion. It really has become a bloated mess of a program.
What does she need iTunes for? Just music and movies? Anything that you've purchased can be downloaded to the phone directly.
Yes, it has become quite ridiculous in the past couple years.
