So interesting to watch this video in retrospect. It spells out the early origins of the “app” notion, the idea of apps for work…and stretching it, “social” networks when Jobs refers to Interpersonal Computing (IPC). Thinking that the AppStore was the first idea of an app, is missing out on fundamentals of the same notion.
A related read I came across is that by Donal Norman (1991). More about it here – http://www.amazon.com/The-Invisible-Computer-Information-Appliances/dp/0262640414
