Command-lines are faster and more flexible than GUIs, because you define your own workflow - you can chain commands together with the unix pipe, pass arguments to commands that are the result of other commands via the backtick and a lot more cool stuff like that. Also, you can type faster than you can point and click. I prefer to keep my hands on the keyboard where I need them rather than having to reach out for the mouse, which is really far away if you think of it - it's 20cm aprox.

Besides, there's a hacker component in using a cmd, because it teaches you how things really work instead of covering that up with a pretty interface that does the job for you.

If these reasons didn't excite you, then maybe you are simply not a cmd guy - which doesn't discredit you as a hacker, I guess. Hackers build things, no matter what their tool of choice is.
