论坛里牛人多，xhy就是一个。在一次论战中（http://forum.ubuntu.org.cn/viewtopic.php?f=105&t=176262&start=15），他说道：

Linux is for people who want to know why it works.
Mac is for people who don't want to know why it works.
DOS is for people who want to know why it does not work.
Windows is for people who don't want to know why it does not work.

实在是高啊。
