Some people like graphics, other prefer a command prompt. Some enjoy tweaking while others just want their job done, thats not bad! Some wants functionality while others funfare! People are usually different and so, want different things. Windows, MacOS, Linux, BeOS and the rest of the guys just covers specific needs and wants.

Its when you try to persuade others that YOUR taste is better than THEIRS that creates problems.. you cannot argue about taste! :-P
