It isn't a fair comparison. Lumia is available in many more countries than N9 and and being churned out faster than N9. But in terms of profits I don't think N9 will do too badly as Nokia is probably making more from an N9 than a Lumia. I don't see consumers taking to Nokia's WP7 phones in large numbers as there is really nothing to make them stand out from other WP7 phones by HTC, Samsung or LG. Having no front facing camera and only 16GB with no micro-SD slots are negatives. Then there's the UI of WP7 which is really very ugly.
