Nokia has confirmed what we've been rumouring for weeks - it will partner with Microsoft to create smartphones running on Windows Phone 7.
The Windows Phone OS will be Nokia's 'primary smartphone platform', while Symbian, its erstwhile solution for the entire portfolio of Nokia devices from low-end to high-end, will be franchised to other manufacturers.
Symbian powers about 200 million of the mobile phones in use, and the Finnish company expects to continue selling feature phones running on the OS - to the tune of 150 million Symbian devices - while it makes the move to the WP7 mothership.
The partnership will see the two companies bringing their best to the table - Nokia with its comprehensive Ovi Maps offering shoring up Microsoft's limp-wristed Bing Maps, while Microsoft's app marketplace will integrate Nokia's Ovi Store - to create "differentiated, innovative products".
"Nokia is at a critical juncture, where significant change is necessary and inevitable in our journey forward," said Stephen Elop, Nokia President and CEO. "Today, we are accelerating that change through a new path, aimed at regaining our smartphone leadership, reinforcing our mobile device platform and realizing our investments in the future."
Meanwhile, MeeGo, Nokia's open-source OS done in collaboration with Intel, is supposedly still on the cards, and will be used as a kind of research tool into next-gen devices. Its lofty plans to ship a single MeeGo product this year - over a year after the OS was first announced - are still a go.
