2. Apple's Maps

Apple makes products that just work...unless they don’t.

Apple completely revamped its mapping software to replace Google's maps in iOS 6. Why? Because they really, really dislike Google, that's why. But it turns out that replacing a complicated service that's taken years to develop isn't the easiest thing to do, even for Apple. Sure, the new Apple Maps looked great; many reviewers loved it.

But there was just one problem: Customers (and developers figured it out months earlier) found the Maps application was filled with errors. And even with the new features like 3D imagery and spoken turn-by-turn directions, Apple's Maps was missing what many viewed as key features like public transit data and Google's Street View.

To his credit, Apple CEO Tim Cook admitted the software "fell short" and said it would be fixed. Meanwhile, in other iPhone peeves, we are still waiting for Siri to properly call us "rock god."
