While Windows phone had been occasionally fighting Blackberry (mostly by eating popcorn on a chair) as the Canadian firm killed itself by itself (and I do not think the Z30 should change that. Maybe MS should buy blackberry? They aren't worth much at the moment.)
Windows Phone, for the first time, shipped OVER 10 million phones the first time in the HISTORY of Windows Phone going back to the olden days of 6 or so years ago. They also doubled their global market share. Notice the chart:
It is clear that with just a bit more effort, and the fall of the Iphone empire, Windows Phone will be the official 2nd place maybe by the end of 2014. Or maybe that's entirely unrealistic.
