I remember, as a young lad in the 80's, learning how to work on cars. What a magical time it was! Opening up the hood, tinkering, taking things out, putting things back....hours of endless entertainment. Looking at my 2-year old Bimmer now, there's no way in hell I'd attempt any of that. Cars have now become an appliance. Something goes wrong, you take it to the dealership. Too many electronics, on-board computers, etc.
With cars, people want something simple that gets them from A to B. No clutches and manual transmissions, special maintenance or procedures, just "plug n' play".
Computers are becoming the same thing. Those of us who still want to "tear it down" and build it back up or work on it ourselves are an ever-shrinking "enthusiast" minority.
Apple rightfully so ignores our needs, just like Honda, Toyota and pretty much every other bland car manufacturer that makes toasters on wheels.
Computers will continue getting thinner, harder to work on, and more specialized. You know - appliances.
