I changed the name of the thread because it implied that Linux was somehow waiting to be relevant some day. This is pretty silly because Linux is just another version of Unix and has been "relevant" and around for many years, certainly well before anyone had ever heard of windows. I would hazard a guess that most of the early chess programs were developed on Unix platforms and many still are. The really interesting question to me is will Linux keep growing rapidly like it's doing now or will it basically remain just an OS for power users. - Don
