Of course MS is not dead in a way that noone uses them. But think about what you wrote - 75%. In Y2K, you wouldn't even monitor it - of course 99,99% use windows. You might start being interested in the weird trend of some people not using IE by then. This is where they were - the default, good-enough and present everywhere. It's not the case anymore - people have choice and as soon as they realise it, they will not choose MS anymore (as far as OS goes).

Some years ago, I didn't know people who knew about alternative OS-es. These days I don't know people using windows, who aren't considering buying an Apple product as their next computer. In this sense they definitely died recently.
