Girls == Windows && Boys == Linux

Oh, and if you have a girlfriend, don't compare her with Windows. She'll not like it.

Girls and Windows

• Both have a great UI.
• Both consume large resources and do less work.
• Both crash unexpectedly.
• Both are not easily portable on different architectures (environment).
• Both can't work on low resource architectures (environment).
• Both are costly to maintain.
• Both give mostly unexpected outputs.
• Both their working often contradicts with their documentation.
• Both are easily prone to viruses (rumors and doubts) and they (viruses) do spread very fast in windows based networks.
• In spite of all above disadvantages, both are liked.

Boys and Linux

• Both have an average UI.
• Both are robust.
• Both are highly secure.
• Both can be easily modified to support new concepts/features.
• Both are efficient.
• Both are easily portable to any architecture (environment) no matter how low the resources are.
• You can easily guess the output for your input (in Linux just open its code, for boys they are mostly transparent by nature).
• Both provide large support for development (work environment).
• Both are poorly documented.

Can you think of anything else that should be on this list?
