Arnaud Michelet, developer behind the France traffic app on Windows Phone, has provided some statistics regarding device usage and the above graph shows something interesting (particularly for anti-WP Nokia fans). Nokia has been pushing hard, not just only in the UK, but France too. This shows with the line for the Lumia 800 shooting up through the roof, and still climbing steeply after taking the lead from the Samsung Omnia 7.
Should this chart be taking into account as a valid indicator on how well the Lumia 800 is performing in France, it also shows that majority of new owners are migrating from other platforms, since the massive incline is not met by a steep drop across the board for first generation handsets. While these aren't official numbers from Nokia (though they back up previous sales reports), it's worth checking out and feeling good about the data in-time for the festive holiday.
