Here is the headline, and then the link to the longer review:
“The good: Apple iOS 7 gets a complete design overhaul and adds useful features like automatic updates to make everyday use easier. Long-overdue Control Center gives quick access to most-used features. AirDrop and iTunes Radio are excellent additions.
The bad: Besides the massively overhauled design and Control Center, there are few ground-breaking new features. The flat design concept favors space over information so you’ll generally need to do more scrolling to get the info you need. Some new features aren’t available for iPhone 4 and 4S users.
The bottom line: Provided you take the time to find your way around, iOS 7’s new design makes it a compelling upgrade that completely transforms Apple’s mobile OS.”
