In episode nine of the All About Windows Phone Insight Podcast, we kick off the new year with a discussion around to the 50,000 Windows Phone app news. Do these numbers have a meaningful impact? Our second discussion points is around the arrival on the Nokia Lumia 710 on T-Mobile US, but also touches on marketing spend, device positioning and a look ahead to CES. We finish, as usual, with an app pick from each of the team.
