Brandon Watson interviews Andrew Clinick, Lead Program Manager, one of the folk behind the new app platform. They discuss some of the new features included in Mango, how they achieved the final result and how they tackled problems.
Features discussed in the above video include multiple and improved live tiles for developers, the introduction of multi-tasking as well as what developers want. Some tips were thrown out from Andrew about creating apps for the platform too. A good watch for developers.
