No. Even KDE doesn't match up with Windows' UI. I call it bloatware because it consumer a lot more memory than GNOME and is generally slower than GNOME. But a heck lot more userfriendly than GNOME.
It's slower because it has more features and eyecandy. Turn off all eye candy and it'll run as fast as Gnome, if not faster (I've tried this on an old celeron box).
What I fail to understand is why GNOME / KDE guys want to reinvent the wheel? Rather why dont they adopt what is in existence and improve it? There is no problem if they copy the Windows UI and add their own improvements. It will make transition for first timers much easier.
You say that because you feel that everyone in the world uses windows. There's actually a sizeable number of people in the world (in numbers, not in percentages) who use Mac OSX. We as Indians always used to see OS=Windows and now OS=Windows || Linux. Macs are way more popular in the home user section (not corporate) than what you're giving it credit for.
And if you're talking about the perfect UI experience, you're talking about the Mac OSX, not windows. Its just that Indians have never seen a Mac ;)
Also, we could customize a distro to make it look and feel much like Windows. There was some livecd distro called Phlak Linux I had tried a few years ago that had a "cheat mode" which would make it look and feel exactly like Win2K, Start button and all. I've heard of Lindows, but never seen or used it, so won't comment.
So mimicking can be done; one of us just has to be driven enough to take the effort. That's what FOSS is all about eh ;)
