The way that Nokia is presenting this device, along with the recent comments from Marko Ahtisaari, make it pretty clear that the N9 is being presented as an 'iPhone killer' (that is, when Nokia are bothering to present it to the public at all). I will tell you right now that the N9 has no chance against the iPhone, not because I don't believe it to be a better device, but because Nokia will not be able to persuade Joe Public that it's a better device.

Nokia: "The N9 has a cool and easy to use touch UI."

Joe Public: "So does my iPhone."

Nokia: "But the N9 has an easy to use application store."

Joe Public: "So does my iPhone, and it has more content. Besides, my previous experiences with the Ovi Store suggest that it sucks when compared to the App Store. Why should I expect this to be any different?"
