Microsoft has not delivered what I want in an OS because it would shut down the perpetual upgrade machine.
If you had to buy six cars in succession from the same vendor in seven years, would it speak well of the vendor's quality??
Provide a fast, consistent, stable interface for disk, graphics, and peripheral access. That's about it. Ok, provide a highway on which I can travel 150mi/hour, safely, with a lot of rest areas, cafes, beautiful nature around, and --- I almost forgot --- free of charge. THat's about it.
I don't want my OS to be an all-purpose life enhancement tool. The reason it is only a few hundred bucks is precisely because it is sold to a mass market. If MS were to develop a more specialized system tailored to your needs, it would be in the millions.
Microsoft has not delivered what I want in an OS because it would shut down the perpetual upgrade machine. No, it has not delivered on what you want because, as I am trying to tell you, what you want does not make any sense.
Take a course (or a textbook) on OS design and, while at that something basic on business management.
If you had to buy six cars in succession from the same vendor in seven years, would it speak well of the vendor's quality?? Yes, if the reason were quality. But it is not: it is a notoriously fast rate of progress in this area, starting with the speed (and other aspects) of the hardware.
