The world is witnessing the birth of a new mobile superpower with Microsoft and Nokia joining forces. Comparing the number of Windows Phone 7 devices sold in 2010 (some 2 million) with those featuring Android and iOS prompted me to say that WP7 was still a drop in the ocean of rival mobile platforms, Nokia included.

How things change in just a few days! In all fairness, speculation has been abundant of a mobile marriage between Microsoft and Nokia, and it seems that the rumors were more than true.

The two companies just announced a strategic partnership which involves Nokia adopting Windows Phone as its principal smartphone operating system. Of course, at the same time Windows Phone becomes the core element of the Nokia smartphone strategy.
