geek4 writes "Microsoft is planning to introduce multi-tasking and full integration with Internet Explorer 9 in future updates to its Windows Phone 7 mobile operating system later this year. IE9 on Windows Phone 7 will use the same core browsing engine as on PCs. Microsoft also talked about the importance of multi-tasking, and claims it can now offer fast task switching without causing serious detriment to the battery life. In particular, Microsoft said, this will improve the experience of using third party applications. In a demo, a Microsoft engineer showed how a music application called 'Slacker' could keep music playing in the background while the user moved between different applications. By holding down the 'back' button, users can also see all their recently accessed applications, allowing them to switch easily between them." Microsoft also demonstrated how they're integrating WP7 with Xbox 360 consoles, showing a video of players using their phones as an auxiliary touchscreen controller to interact with a Kinect game.
