Very thoughtful and interesting read. One thing I don't get is "Different apps is like having two devices/second screen." - so this is revolutionary again, after 30+ years of widespread multitasking GUI, because omg tablets? A weird and jarring note - the equivalent of alt+tabbing on a tablet still feels as clumsy as it ever did on desktop; especially now that screens are large enough to support multiple apps.
