Microsoft has got a huge monopoly. Everyone knows that but who cares? They were first to mass-distribute an OS that had a GUI, had a stack of applications to go with it, was ready for the net, came with a browser, and ran on a IBM compatible PC (don't here that term used much now ay) which was the type of computer making the most inroads in the market share stakes.
That is what I said re: your accusation of untruths. Please don't insult my intelligence by ripping a sentence apart to suit yourself. Take note of MASS DISTRIBUTE and the other things included in the sentence please. When you then consider Apple's effort you'll realise their systems, by comparison, were never mass distributed. Nor did anything else apply that I mentioned.
