Gizmodo managed to wheedle some kind of answer regarding multi-tasking on Windows Phone 7.
The answer, from Joe Belfiore, the director of Windows Phone, was â€˜complicatedâ€™:
"The core operating system is a modern multitasking operating system. If you play music for example, the music will play back as you navigate around the experience…if you’re using email, we have great support for push email and that happens in the background.
For third party applicationsâ€”we’ll get into a lot more detail on this in MIXâ€”but we have a few ways we’re going to make sure that third parties can bring their value to the user even when the app is not running. Live tiles are an example. Data feeds in the hubs are another example for some apps."
