Microsoft is cutting an additional 2,850 jobs on top of 1,850 announced in May 2016, meaning it has laid off over 10 percent of its workforce in the last two years. Most are ex-Nokia employees from its mobile hardware division, it said in its annual SEC filing. That means Microsoft has almost nothing left of its $7.2 billion Nokia acquisition, originally intended to make it a smartphone hardware player. The software giant has already notified 900 of the employees and will complete the remaining layoffs by mid-2017.Microsoft's mobile phone plans are a big question mark, as sales are in a free fall. The only ray of hope for Windows Phone fans (if there are any left) is that Microsoft hinted last year that it needs to make a mobile device as good as the Surface line. A "Surface Phone," however, is still nothing more than a rumor and if it does come along, would likely be aimed at Microsoft's core business market and not consumers. With layoffs now totaling 12,100 in two years, however, Microsoft seems to want nothing to do with building smartphones.
