I still believe that programming is not for everyone. There's experimental evidence that programming classes have two bell curves--the ones who think right and can succeed, and the ones who don't. More personally, I've tried to teach CS at various levels, from primary school to university level, and the divide can be very clear. It isn't about ability or intelligence or background, some people simply seem to be unable to think in the right way, like the mental model in their head is trying to match on the wrong criteria for this specific area.

So, essentially a Specific Serial Buss? We'd be going back to pre-USB times, except without the advantage of differently shaped connectors.

You could build one layout using relative positioning and have it scale to each of those easily. If you want different layouts for different devices, this is an option, but by default things won't break unless you're explicitly positioning things absolutely instead of relatively.
