I do not think that anyone ever anticipated the advent of free user supported software, or that it would become the dominant business model. Linux has achieved just that and it is a certainty that the whole body of classic applications is also well down the road. Essentially step by step the Microsoft business model is been driven from the field proving once again that monopoly is not immortal. A huge reason for this is simply it capacity to last and last. Soon every coder becomes a linux coder
i realized today that my own reliance on micro soft has been steadily declining as the operating system becomes increasingly invisible.
So yes we are all migrating to Linux platforms and not even noticing.
