You can run proprietary drivers with ReactOS since it replicates the driver layer too.

So unlike Linux systems with Nvidia Kepler cards, you can still run the most up-to-date desktop environment. Or if you have an obscure WiFi card, you can use the Windows drivers.

This, I'd love to be able to use Genelec GLM from Linux but it needs some custom serial drivers... too bad it only supports Win 10 right now.
