Microsoft Desktop Player aggregates content across various Microsoft properties and maps it to your role as a developer, IT Pro and IT Adoption lifecycle. Also if you configure the local settings you get local IT resources like your Developer or IT Evangelist in your area, local user groups, local training resources to get your certification etc.
(In Phase I the local settings are US only)
In addition it streams breaking news from MSDN/TechNet to the desktop player. One additional advantage for site publishers is it can be embedded in their sites to give their readers rich content via the embedded player.
