That's really neat if it works out. But doesn't this mean that users have to own a copy of Windows to use those drivers legally? Maybe they can download some drivers from manufacturer sites, and maybe some of their EULAs don't require the user to own a copy of Windows, but I'd be surprised if many users could run a machine with only Windows drivers without any of the drivers included in Windows releases. But even if that all works as well as it does in Windows, it's still inferior to Linux. Users are stuck with whatever binary drivers they can get, and whatever reverse-engineered, bug-for-bug compatibility the ReactOS developers can manage. It would be much better for users if they could run WINE on Linux.
