The iPhone 4S is definitely an iterative upgrade, but it refines what was already one of the top smartphones on the market. The display still cannot be beat (assuming you're fine with the screen size), the performance and speed is smoother than anything out there, the great camera from the previous model gets an 8-megapixel upgrade (with improved white balance, thankfully), and Siri quickly becomes an everyday go-to feature, even if it doesn't have as much functionality as one would like.
That said, there are still weaknesses here, and they primarily stem from the operating system. While iOS 5 brings some features that have been available on other platforms for years now, the implementation isn't always perfect (yes, click-to-clear notifications tray, I'm looking at you) and basics like Maps.app are looking long in the tooth — especially when Android offers such a great turn-by-turn solution. Overall though, it is hard to argue with the breadth of the ecosystem, the beauty of the physical design, and the general consistency the phone offers.
