Want to install Safari on your Windows PC? Hope you don't mind violating Apple's Software License Agreement. Apple's lawyers messed up when they copied and pasted the license for using Safari for Windows. From the text of the SLA:"2. Permitted License Uses and Restrictions. A. This License allows you to install and use one copy of the Apple Software on a single Apple-labeled computer at a time." Whoops! You could run Safari for Windows on an Apple, I suppose, using Boot Camp or virtualization software. But somehow I don't think that's why Steve Jobs had his programmers rewrite the browser software for PCs.
The iTunes for Windows license (PDF) has no such restriction: "2. Permitted License Uses and Restrictions. This License allows you to install and use the Apple Software."
