Ken Yarmosh makes good points, regardless of your stance on iOS 7:
The analysts have stated that Apple has lost it’s ability to innovate. Anecdotally, I hear comments from friends and family that the iPhone is no longer new or cool, with regular questions about whether to buy an iPhone or a Samsung device. So, whether your initial reactions to iOS 7 are of love, hate, or indifference, iOS 7 is exactly what Apple needs right now. It’s exactly what iOS designers and developers need right now. And it’s exactly the kind of change only Apple is insightful and bold enough to both recognize and make. It’s time for a change.
