>Second, Google believes that the browser market is still largely uncompetitive, which holds back innovation for users. This is because Internet Explorer is tied to Microsoft's dominant computer operating system, giving it an unfair advantage over other browsers. Compare this to the mobile market, where Microsoft cannot tie Internet Explorer to a dominant operating system, and its browser therefore has a much lower usage.
By the way, I think it's absurd for Google to threaten that they may now charge a license for Android [2]. They're effectively saying that now that they've eliminated all competition over the past 10 years and achieved a dominant share of the market, they're going to raise prices. That's a slam dunk case even in the US's broken antitrust system.
