Why is nVidia all of a sudden evil? As a company, they did nothing wrong. They executed well, and formed OEM relationships well. 3DFx died beause it messed up, this is all free enterprise.
However unfortunate this is, noone did anything bad. nVidia just conducted themselves the best. Monopolies are illegal, if there is unfair competetion, which there wasn't. nVidia had everything against them, ATi had more resources, and 3DFx had the name, but they still won. Fact of life.
And for those of you who complain about 500 dollar video cards, BUY A CHEAPER ONE. nVidia makes those too, and those give great bang for the buck. Just because they offer a high end product doesn't mean you have to buy it. Comparing them to Microsoft is unfair, because you can't buy a cheaper version of windows. Look, there are people out there who have the money to spend of that stuff, and they shouldn't be denied the right to spend more and get a better product, jsut because most can't afford it.
