The App Store is one of the key strengths of the iPhone. You can easily find, purchase and install applications that increase the utility of the iPhone. Steve Jobs claims that more than 100 million downloads have occurred in the short time that the App Store has been around. I’d bet that if you were to take all of the other smartphones and add up every download, you still wouldn’t hit 100 million.

My nit with the design is that when you update applications, the app icon on the phone doesn’t stay put. In fact, the iPhone 2.1 update scrambled the order of all my applications. That’s the kind of detail I’d expect Apple to get right.
