One of the most enticing "what-ifs" of recent years has come true: Microsoft has purchased Nokia's devices and services unit, bringing the Lumia lineup under the Redmond roof. The move unites Windows Phone 8 with its biggest hardware supporter, giving the company the integrated mobile offering it's been looking for with Surface and other devices. When the deal closes in the first quarter of 2014, Microsoft will pay 3.79 billion for Nokia's business, plus another 1.65 billion for its portfolio of patents. (The 5.44-billion total is considerably less than Microsoft paid for Skype in 2011.) 32,000 people are expected to transfer from Nokia to Microsoft, including 18,300 that are "directly involved in manufacturing."
