CONVIDADO

Analogia interessante que o usuário "mlvezie" fez na seção de comentários de um post do Lifehacker:

My feelings for Windows now is that, even thought I've used it for years, and certainly know my way around it, when I use it, I feel like I'm a guest in a friend's home, but when I use Linux, I feel like I'm at home.

Faz sentido.
