NewsFactor has a brief analysis on Windows vs. Linux that hits most of the valid points. One point that I think is undersold is the difference in user experience between Windows and Linux. Microsoft has enough marketshare and longevity for there to be quite a bit of human capital build up around the world on operating (and administering) Windows. Displacing this human capital is going to take a distruptive kind of jolt. Just because you come up with a better interface doesn't mean the world will beat a path to your door. Is the QWERTY keyboard the best keyboard design? Just looking at a side-by-side comparison of the two operating systems does not account for the dynamics required to create a change in inertia.
