It should be given the same level of expectation as the thing it replaced. If Apple had run this maps app as an optional beta program, and not replaced the google maps app, things would have been a whole lot better. Then they could've waited for iOS 7 to make it default, just like they did with the messages beta for OS X.
This makes very good sense. A gradual migration rather than a shock transition would not only have saved Apple's arse but also the consumers & the overall user experience.
