Well, I wouldn't replace my win machine, but I don't really have any excuse for not setting up a linux box to act as a development environment/firewall/etc.

That aside, I doubt that I'd want to implement the kind of path-structures one typically comes across on an ISP's CGI-server

(OT) IMHO the world would be a happy shiny place if all desktops were windows, and all servers were linux, BWTFDIK?
