Do they? I think most consumers assume if a 40 cent part breaks on their computer they will pay 40 cents plus labor plus some part markup - the same way car, HVAC, and other repairs work.

That's why when people's computers break they take them to get repaired in the first place. Otherwise, consumers would just be tossing their broken devices and buying a new one.

If you're fairly well-heeled you certainly have the privilege of forgoing repairs and just buying new ones. Lots of tech enthusiasts who cycle through devices every year probably aren't bothered. But normal people who don't get excited at the prospect of purchasing a new 3 or 4 figure device appreciate being able to get their machine back in working order for a few hundred max.
