And it doesn't actually work reliably, at least on Android. My wife and I frequently don't get notifications from specific apps, only once we open them. My impression is that the platform just changes too frequently with regards of what you have to do to work well even when you're killed. Also, especially for push notifications, your now at the mercy of Googles service to delvier them to your app (not sure how the open source variants do it)
