Although iOS 6 has generally been classed as a triumph and definitely represents evolution of the software, there are still some users who feel that Apple has regressed with certain aspects of the firmware. Long time iOS device owners are used to firing up the Maps app and getting information fed back from the trusted Google Maps service, something that is non-existent in a stock installation of iOS 6 thanks to the inclusion of Apple's own vector-based mapping app. Some people just don't like change, and if you happen to be one of those people then the ClassicMap app on the App Store might be what you need.
