In episode three of the All About Windows Phone Insight Podcast we start with a brief summary of three news stories: IDC's developer engagement report, the Nokia Lumia 800's retail availability and arrival of Internet Sharing on certain second generation phones. In our main feature Ewan points out the tenth anniversary of Xbox and asks what we can learn about Microsoft from it, which gives Rafe and David a chance to debate the merits of Microsoft's software ecosystem building ability. We finish with an app pick from each of the team.
