Take section 26 of the complaint:

"For example, the iPod did not achieve widespread adoption until Apple developed a crossplatform version of the iPod and iTunes for Microsoft’s Windows operating system, at the time the dominant operating system for personal computers. In the absence of the consent decree in United States v. Microsoft, it would have been more difficult for Apple to achieve this success and ultimately launch the iPhone."
