Let's say that going WP was the right choice. Now convince me that announcing it one year before baving anything to show was worth it. And that not selling the N9 everywhere while there were still no Lumias was the right choice. And that not waiting to launch on WP8 directly was correct. And not allowing first-gen lumias to upgrade was sane (which could clearly be done, Wp8 on HD2 is a testament to that), and not bringing loved features like lpm earlier was ok, and marketing Lumias to teenagers alienating the traditional Nokia userbase was the correct course of action. And many more... (europe vs US targeting, old hardware specs, abusing PureView name etc.)
