Well, actually they have a new model. I call it the "Apple" model. Low volume sales on high value items where you can charge more.
Even NVidia has moved to this model: make your money from selling high-end GPUs for Data Centers and forget the low-profit margin (GeForce) GPUs for gamers/consumers.
The whole economy is moving to that model for many things.
Apple has low volume sales? You might have picked the wrong company for that example. Nvidia in the consumer market might fit, I would agree there.
Auto sales, airline ticket prices (notice the expansion of 1st, business, and comfort class seats), etc.
