We've reported that Microsoft is taking mobile music more seriously, and that even Steve Ballmer thinks mobile Web browsing needs some improvement.

Enter J Allard, who has been promoted to "Chief Experience Officer" and "Chief Technology Officer" (and who has one of the coolest bio mugs out there).

You may know Allard from his previous work with Microsoft on the Xbox, the Zune, Windows NT and, everybody's favorite, TCP/IP (among another 30 or so products).

Windows Mobile is now under his auspices, which should lead to some promising developments for our beloved, but oft maligned, operating system.

From his updated executive bio:

J Allard is responsible for the technical architecture and user experiences related to products and services of the Entertainment and Devices (E&D) division. Allard works closely with technical leaders across the company to align E&D product teams with Microsoft's overall services strategy and product architecture, and drives the technical and design agenda to deliver Connected Entertainment experiences for consumers.
