I think ReactOS is what are you waiting for. It suppose to offer you the freedom of any other free and open source OS while holding the benefits of Windows. But it also awaits contributions. Spread the word.

ReactOS is poorly supported, incomplete, and user-hostile. Very little actually works on it--the software support is mostly limited to fairly old software, the only development happening for it is OS development (which is fine, but that's not a lot of use for normal people, or even software developers who don't have a burning desire to reinvent the wheel), and its UX decisions are a noted step backwards from Windows itself.

I don't intend to be rude, but recommending ReactOS as a legitimate Windows alternative is reality-averse.

"ReactOS is incomplete" = still needs development attention, which is what I've said - "it also awaits contributions". "user-hostile" as much as Windows has ever been. "Very little actually works on it" is actually more than what works on Linux + Wine, which at it's turn (like many would claim) do cover enough needs already, and that's only the "alpha stage" we're talking about here. ReactOS is getting better and better at the fastest pace relative to the rest of the OSS. You see, even if the ReactOS project had to start right now, it would still have a guaranteed chance of succeeding thanks to it's principles: it is free and open source like any other "free-as-in-speech" option out there, plus the one thing that makes the difference - it avoids alienating the users by breaking the backward binary compatibility for the sake of whatever reason. It offers the Windows simplicity.
