Los de Color Azul son los de windows, los negros de linux.

Esto es mas o menos una comparación... Ustedes ya saben, ni búsqueda incansable, ni crack, ni serial, ni inestabilidad... software libre y seguro.
Tambien pretendo que los que sepan algo mas, lo adjunten, que yo lo agrego a la lista de "comparaciones".
