I’m loving the change to iOS7. One thing that comes to mind with how beautiful and integrated some things are to the OS (For example, you can access a flashlight from the Control Center which made my flashlight app obsolete), is how Steve Jobs would think of this. Beauty and design were important to Jobs. I believe iOS7 would have been welcomed by Jobs.
There are errors to iOS7, but there seem to be errors to every new system if it is forward-thinking enough. I do happen to think that the iPhone 5S would have been destroyed by Jobs. There is no way that a fingerprint scanner would have been welcomed by Jobs, and hackers have set prizes on being able to hack the fingerprint scanner first.
