"When eWEEK Labs looked at Internet Explorer 6.0 more than five years ago, we were so disappointed in the browser that we said the only reason to upgrade to it was because it was free. That means you'd have to go back nearly nine years to find a release of the Microsoft browser that we found to be significant: IE 5.0. But with the release Oct. 18 of Internet Explorer 7, Microsoft is finally back in the Web browser game in a serious way:
IE 7 takes major strides in reversing Microsoft's neglect of the flagship browser." And,
surprise.

It's a compatibility layer. There's no Windows code involved.
So actually IE does run on other OSs
No it doesn't. When people say it runs on other OS, they mean natively, not through an emulator or equivalent, especially on a unique architecture (x86).
The reverse-engineered Windows code involved is in Wine, the rest is in IE. Or if you prefer, Wine is not an OS.
