I extend your line of questioning to display it's absurdity
- Why doesn't everyone focus on writing good apps for Windows instead of Linux? - Why do companies waste time developing non-intel processors? - Why do people around the world waste time learning/reading/writing/speaking non-english languages? - Why do students waste time doing problems listed in their books instead of inventing new problems? - Why do we need a dozen search engines? - Why do all these little countries need their own government? - Why do we need all these programming languages. Can't everyone use Java for everything?
