OS itself is nice, just like FreeBSD, which is the base, but can't agree with this:
Even though I prefer WindowMaker for my desktop, I still must have the KDE software installed. There are just too many nice tools: Kate, Kompare, Konsole, Umbrello, Konqueror, and the best of all is the integrated remote login management, so you can browse, edit, and save files locally or via SFTP/FTP/Samba/NFS without even thinking about it. No other desktop suite offers anything remotely as flexible.
