That only works with large screen space. On smaller devices this is not very useful.

As you mentioned, background tasks are possible on Android, by creating a service. Yeah, at least it is possible, unlike other popular OSses, but it adds to the complexity of programming. Writing something like an SSH terminal becomes quite a bit harder.

I guess Jolla will maintain the normal Android behavior for Android apps. I can't see much benefit in keeping Android apps running in the background, as they are written (or at least should) to handle the suspend/run/suspend-sequence. An option to override this per app would be nice though.

But what about Android widgets? Can we forget about them? Or do we get to see a Sailfish app which hosts Android widgets?
