Microsoft [3] kicked off E3 with a packed list of announcements this morning across its mobile and gaming [4] platforms.

First up: music. Microsoft announced the launch of their new music service--Xbox Music. After the demise of the Zune player, it looks like Microsoft is refocusing its energies in a different direction.

Microsoft also announced a new partnership with Nike to create a fitness training system on the Kinect. The motion capture technology on the Nike+Kinect Training [5] is rigged to provide better performance statistics and record and report feedback on workout techniques.

Xbox SmartGlass [6] was the third product announced today--one that would integrate TV watching on the Xbox with all major mobile platforms--iOS, Android, and of course, Windows [7] devices. TV on a device will pick up where you left off watching on the Xbox, and will be enhanced. For example, while watching Game of Thrones [8], a map will track the dense and well-dispersed narrative through the series' fictional setting of Westeros.
