The Next Web noticed a correlation between the number of active users of the Facebook app for Windows Phone 7 and the number of users of Windows Phone 7: there is a new user of this application all WP7 6.756 smartphones sold. In January 2011 the site was estimated that 2 million WP7 smartphones were sold, a figure confirmed a few weeks later by Microsoft. If this ratio still holds, there are now 12 million Windows Phone outstanding.

The Facebook application for Windows Phone 7 is indeed actively used by 1.9 million people: it is thus slightly less than 13 million Windows Phone that would be activated, a figure reduced to 12 million by the site as a precaution. Of course, a ratio also resists simplistic poorly to the test of time, especially since a second-hand market is set up. However, we note such a peak usage of the Facebook app for WP7 from the marketing of the first Nokia smartphone Lumia, which tenderait to confirm the positive impact of the Finnish manufacturer of mobile ecosystem of Microsoft.



Nevertheless, the need to look at any cost figures shows that the release of Microsoft is deficient: the Redmond company has only very rarely communicated to the sales figures of WP7 devices. If the estimated 12 million was good, it would show in fact that Microsoft is far from having won his bet to become a major player in the telephony world: it takes months to sell as many Apple iPhone. History shows, however, Microsoft can do the back round and continue to invest: hope for the Redmond company that WP7 will be more than Zune Xbox.
