&gt; if there&#x27;s something I want an OS to do that Linux can&#x27;t do, I would be motivated to work on making Linux able to do that thing so I could do that thing on an Open Source OS I enjoy using, rather than work on replicating Windows so I could do that thing on an open source OS I don&#x27;t enjoy using.<p>That&#x27;s a great ethos, but it&#x27;s not that Windows can do something Linux can&#x27;t. If you want to play a game&#x2F;use a CAD made only for windows, are you going to pour years into cloning it? Yeah, Linux has, at least, competent applications for almost every need, but sometimes what you want just isn&#x27;t available.<p>ReactOS is shooting for the moon, but if it took off and got to an almost 100% windows-compatible state, I&#x27;d be glad to have an Open Source Windows.
