> I like the ReactOS idea, but I think it will take decades to be compatible enough - and I'm even talking about enough.

It has been under development for decades. That is more than twice the time it took to develop Windows 95. I've tried ReactOS a few times over the years, and it has never worked for me.

I know of two specific examples of ReactOS code that as of a couple years ago were identical with Windows code. There are likely other instances pointing to a non-clean-room implementation.
