without disagreeing with your statement "Only spatial computing apps matter", there are two other considerations: Nobody knew what the point of a microcomputer was back in the Apple II days (at the time I thought it was crazy that anyone would buy a computer rather than design and build their own). The best anyone could imagine with was keeping recipes and playing games. Yet the killer app was Visicalc, with analysts and accountants buying their own (expensive!) apple IIs and visicalc and getting around MIS (what's called IT these days). The second consideration is "onramp". Clicking a button and being able to experiment with an app you've already written yourself is way better than being given sample code. Likewise the crufty skeuomorphic cues (from the desktop metaphor of PARC and then the Mac to the "leather" of the ios notepad and shiny "wheels" of its date picker) are important onramps that get people using something so that they can develop the correct metaphors. It wasn't Apple who came up with "pull to refresh", it was the developers (Brichter's app Tweetie, then quickly adopted by others). So while you're right in the long game, I think your dismissal is premature.
