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.
