* The purpose of going to college is not to learn a discipline and go out there to make a living out of it. College teaches you how to *think* and stand on your two feet when you face situations. I do not necessarily agree with learning a particular system like Windows, UNIX/Linux, Mac, or a particular language. However, I do have to say that Computer Science students need to learn and be exposed to a lot that is out there today: Windows, UNIX/Linux, Mac, C/C++, Java, Perl, etc. It may seem like a lot, but that is Computer Science. The goal is to learn how to think when you are in the situation of moving from one platform to another (whatever that may be). You need to be FLEXIBLE.

* Few people admit that it is necessary to learn the command line editor :-) I do have to say that the mouse is one of those inventions that actually make your life sometimes a little more difficult (sometimes an unproductive tool).

* It is hard to have Linux as your only operating system. Two words: desktop standardization.
