Personally, I strongly prefer Unixoid systems, too.<p>But in my day job, I am a Windows admin (and helpdesk monkey). If there was a system that is both free software <i>and</i> binary compatible with Windows, that would be pretty nice, if only to give Microsoft some competition.<p>And on the corporate desktop, Windows totally and utterly dominates. Replacing it is next to impossible, because most of the applications (at least in our case) are not available for other systems. So a free software-alternative that maintains compatibility would be really nice.<p>(Of course, ReactOS is aiming for XP-compatibility, so even if they reach 100% compatibility, they still have a long way to go...)
