The courts didn't finalize anything, except in a restricted legal sense, and there was no general consensus on such questions before or after the courts gave their opinions.
Few people dispute that Microsoft has a dominant position in a handful of key markets, most notably in PC desktop operating systems. Whether or not this is a monopoly or a harmful monopoly is a much more open question.
Intel has a comparable market share (currently around 81%, vs. 94% for Microsoft in the desktop OS arena), and yet it does not appear to raise so many questions of monopoly. I think in part that is because the average geek cannot fancy himself building a chip fabrication facility and competing with Intel, whereas many geeks like to imagine building a software product that somehow competes with Microsoft. And many more geeks would like to work for Microsoft, which is more willing to hire people with no education. Chips don't engender the same emotions and envy, in any case.
