Before I started working with *nix like systems, I always wondered who those idiots were, typing '/path/to/anywhere/and/lots/of/maps/away -iit -ijg >blabla' to get something running, when you could get things done with just one click 😉 . Now, about 5 years later, I get extremely annoyed when my 'user friendly' GUI freezes and some installerscript is as flexible as the Eiffeltower, and remote system management gets a new meaning when you try to rdp through a dial-up connection on site somewhere. 😱
What the sysadmin knows, is what he likes best. I try to force myself to keep the practice with windows up, but it just irritates me like **** .Having said that, I know that system/network administration without windows is unthinkable, and that major companies wouldn't get things done without windows (even though there are alot of other solutions available).
So, I feel best with *nix systems and am working on my feelings for windows. Since OSX is 'just' a linux flavour, I see no reason to give fruit advantange over the rest.
