Windows Phone Thoughts: Windows Phone 7 Series Push Notifications

"Microsoft's flavor of push notifications for Windows Phone 7 Series -- the so-called Microsoft Notification Service -- was just demoed using an MLS (Major League Soccer) app, and it fits in really well with the "Metro" UI motif."

I've never used Exchange or a Blackberry, so I don't know how different this is from the current WM6.5 paradigm. What's disturbing to me is that Engadget are speculating that this is just one more nail in the coffin of multitasking on Windows Phone. While I like the Metro UI and most of the other changes coming with WP7S, this is one development that has me worried.
