iOS 7 was designed to attract female clients. Nothing else. Everything about iOS 7 says I am feminine.
1. The bright color scheme, full spectrum of colors and soft pascal look instead of the darker, solid tone of the previous theme.
2. The sexy look of the new theme and women love sexy look.
3. The thinness of the number 7 (women want to be thin)
4. The constant beautiful women expression throughout the presentation.
It makes logical sense. Go after the women.
They know apple fans will not switch. And they know that they have a pretty good portion of the men that will stay with iPhone based on the satisfaction surveys. And most men want big fatty phones, and another segment of geeky men want the ability to tweak and have widgets and customization.
So, no reason to continue to create a phone to impress those men when they're not going to switch.
But if you create a UI that is feminine to attract females from the competition, and those women are married, their men will not have no choice but to buy an iPhone because of the family pack deals. And we all know when decisions have to be made between the husband and wife, the wife always comes out the winner.
Apple wins in the end! Interesting!
