I'd rather have Windows look-and-feel planted on top of OS X and I think most Mac users would concur.

Your kidding... right?
Sorry, but you can count me out.
The Windows look and feel is the single worst part of Windows. The application environment (rooted apps) works against multitasking. The designers went against the best UI concepts to seem different than Macs.
On the subject of WINE...
Personally, I'm glad that WINE is limited to an X Windows environment, because that is where it should be. If it were a better environment (more integrated), then we would run the risk of developers not making Mac apps.
This was the problem with OS/2 Warp. It was able to run Windows apps, so developers didn't bother to make OS/2 apps.
Our application environment, our user interface is what sets a Mac so far apart from Windows. I surely think anything that brings us closer is a bad idea. Running Windows apps on a Mac would count as such... and absolutely having the
Windows look-and-feel would be.
Contrary to some people's beliefs... the look of hardware has little to do with using a Mac. It may have something to do with initial purchases for some, and a larger part for those with portables, but most people don't spend time sitting looking at their hardware. They spend their time interacting with the operating system and the applications.
If Apple made the ugliest boxes in the industry, it wouldn't stop Mac users from using them (though it might slow people switching), and that is because once set up, a computer usually disappears into the background while it is in use.
Jobs said it himself... the
Mac is the OS.
As for the underlying operating system... We shouldn't forget that the foundations of the Windows NT line was OS/2. While not as good as what we have now, it is still a very good core OS (despite what Microsoft has done with it).
