i used 3 generations of windows on my phone; and am sick of this coming again and again. yes microsoft has some leverage due to its desktop monopoly(and office) but it must see that it is impossible on mobile to get any traction despite billions spent on marketing, to nokia etc. msft should better focus on developing software on android and ios; they just can't do it.
