Say what you will about the dual personality of Windows 8.1 but there are some things it does better than the mobile competition.
Microsoft decided to take on the mobile space with a frontal assault, and that's what it's done with Windows 8.1. As an OS that works on any type of PC, the company had to make sure that mobile was properly addressed as it is a hot segment.
