"So that brings us to the Nokia perspective. I have argued that Stephen Elop made a massive strategic error by choosing Windows Phone over Android; coming from Microsoft, he failed to appreciate that Nokia’s differentiation lay not in software, but in everything else in the value chain. It would have been to Nokia’s benefit to have everyone running Android, including themselves. Everyone would have the same OS, the same apps, may the best industrial design, distribution, and supply chain win. Elop threw it all away."
