'Operation Elop' and the bungled transition
(All About Windows Phone)

Authors Pekka Nykänen and Merina Salminen published a book in Finnish, back in 2015, about the fall of Nokia from 2010-ish through to the (then) present day, 2015. The central character in all of this was Stephen Elop, as you`ll have guessed from my headline. It`s a very long book, but it has now been translated into English and is available for free. See the quotes and links below. It covers the latter Symbian years, the still-borm Meego, the switch to Windows Phone and the eventual decline and sale of the vast Nokia empire.
