My initial thoughts of XFCE on FreeBSD

Then used openbsd at work. And Solaris/redhat etc.
Until Ubuntu.
It's just so darn easier for most things. And it just works. Debian++.
Still like installing freebsd once in a while on a VM to tinker on, and some services are probably still best run on it comparing to others.
But using freebsd as a desktop? .. not sure I'd go that far.
