atomic tofu - what?
"Anything can replace Windows if it is designed to do so, from product but more importantly to marketing."
most linux distros are free, how are they to be marketed?
Windows monopolises the OS and particularly the home OS market because they make dramatic threats and business moves in order to prevent people from knowing and using alternatives. When 3.1 came out there was another OS called Geoworks. Geoworks was way better that 3.1 but it still disappeared because microsoft threatened to stop supplying DOS to manufacturers who put Geoworks on their machines. Microsoft then took legal action against Geoworks saying that they had stolen their 'style' when in fact geoworks was working in Apple and commodore before windows was released.
there are loads of other examples of things the Microsoft does to keep itself where it is that have nothing to do with being a better product but this is one that i was reading about recently
Windows Vista (Dinosaur Sightings: Windows splash screens from 1.01 to Vista)
basically in my opinion there is almost nothing in your post that is entirely correct but im not going to go through it all
