So I remember trying this before, and it had a 'desktop' and an app store where you could add more apps, but right now the demo seems to be limited to documents and presentations.
Is that a change in focus or a limitation of the demo?
Yeah. I've been focusing on office apps rather than "any apps", and I removed the window manager based on feedback here and elsewhere that it felt too "heavy" and unnecessary. Also, the app store was actually the Firefox OS marketplace, which was shut down. (And to be honest, the apps in it weren't super useful for Airbon to begin with. There weren't very many apps for "serious work".)
Under the hood, it's theoretically still super easy to add/install apps in Airborn, though, and Firefox OS's marketplace server is open source, so maybe in the future?
I can agree with that, the window manager was really neat (as I've always indicated these sorts of cloud platforms are like virtual OSes), but probably didn't add much to usability.
Performance seems really smooth, I'm glad to see this is still coming along quite nicely.
Even if it isn't the best UI, I think you really do still need to get something like EtherCalc on here, even for personal use, I love spreadsheets for storing structured information, and for business users, it's almost definitely a need.
