Yes, there are two different big things that I left completely out of the scope: desktop and state preservation and sharing. I was going to explain it separately if Jolla is interested.

Basic state preservation and sharing could be seen in Firefox Sync, but it is not reliable :-( And we need that for IM, ebook readers, media, whatever else..

And I have to admin Harmattan sucked exceptionally bad when it comes to properly handling the environmental state. Just a simple rule "never drop older version of the information until you completed receiving replacement" meant nothing to developers as it seems. Drop off the network by accident and you lose state and data all the time.
