As expected, Nokia's devices and services business has been officially acquired by Microsoft today. The date was set earlier this week, and it seals the deal the two companies entered into last September. Nokia has long been allied with Microsoft, committing fully to Windows Phone, but as explained when the merger was announced, Microsoft's new arm will continue to support feature phones like the Asha and Nokia X ranges, as well as smartphones (we'll have to wait to see what "support" means exactly). The obligatory press releases from both companies don't reveal any grand plans or shift in focus, but each side has issued some closing remarks, if you like.

Microsoft CEO Satya Nadella said:

"Today we welcome the Nokia Devices and Services business to our family. The mobile capabilities and assets they bring will advance our transformation. Together with our partners, we remain focused on delivering innovation more rapidly in our mobile-first, cloud-first world."

Stephen Elop, former Nokia CEO who's moved over to become head of Microsoft's hardware division, penned an open letter with similar sentiment:

"As Microsoft and Nokia Devices and Services come together as an expanded family, we will unify our passion, dedication and commitment to bringing you the best of what our joint technologies have to offer."
