Today, as it rolls out to users everywhere, iOS 7 is still on most levels the same operating system it's been for six years. Meanwhile Android has become a fun, efficient, flowing operating system that makes it easy to move data between apps, easy to share things, and easy to see only the information you need at the moment. Where iOS 7 still feels like jumping in and out of a series of apps, the best moments of using Android make it feel like a cohesive, unified platform. There's no question iOS 7 has the foundational strength to match that experience, but Apple has to throw open the doors and let its huge ecosystem build on that potential.
iOS has always been an excellent operating system, and iOS 7 remains an excellent operating system. But if Apple's goal was to match the power and flexibility of its rivals, iOS 7 feels very much like the beginning of a project rather than its conclusion.
