Earlier quoted context omitted.
Could you explain a little more why you feel that way?
First and foremost, dependencies. My apps cannot have third party services that it relies on. that would give too much problems with our own SLA's. If the SAS goes down, you are responsible. Second: my stuff needs to be able work offline (at least o some degree) :)
Secondly, we definitely want to support offline capabilities (as a web app still, but it's very possible) and the ability to safely store all of your work :)
