You might have noticed a brouhaha over map accuracy in iOS 6. Nokia undoubtedly did, as it's using the iPhone 5 launch to remind us that its strategy has been all about location lately. The crew in Espoo has pitted Nokia Maps from the Lumia 920 against both Apple's equivalent as well as Google Maps -- and to no one's surprise, Nokia's own platform comes out on top. In practice, it's a relatively frank comparison that doesn't try to win on every point. Nokia tends to use a liberal definition of the term "3D" that includes augmented reality, but it's otherwise willing to emphasize its advantages in offline mapping and the sheer scope of its mapping coverage. Apple's very young mapping effort struggles, while Nokia is willing to accept that it doesn't have as much traffic coverage as Google. There is, however, the slight problem of the Lumia 920 not yet shipping: unless you've been blessed with a prototype of the Windows Phone 8 device, Apple and Google are the only ones that have their latest navigation software on a phone you can actually buy. Hit the source for the full, very tall chart as well as a few sly jabs at Nokia's competitors.
Update: To clarify, it's true that much of what Nokia is talking about can be found on existing Lumias. However, Nokia did mention that there will be new features coming to Nokia Maps in Windows Phone 8, including the wider offline support, an augmented reality view during navigation and better integration with Nokia Drive.
