Article says Android and iOS have 84% and 15% respectively of the market. It's still hard to sink in the fact of how strong a duopoly the mobile market is. All of WP, Blackberry, Ubuntu, Sailfish, Tizen, and probably more, all share the same 1%!
A third party platform will fundamentally need to beat Android so badly on platform features directly that app developers rush to it, users get excited about it. The hype has to be real. Maybe that's HoloLens for Microsoft, maybe it's someone else. But the admittedly incremental benefits Windows Mobile has over Android aren't enough to break that monopoly power. Nothing about Tizen, Ubuntu, Sailfish, etc. gets people talking about the cool amazing future of technology.
My understanding is that most? markets function this way? Perhaps someone has some numbers...
