I see a problem here: I'm not obsessing not using the mouse. There are some very loud people out there who are dogmatic anti-mouse. As a result, everybody speaking about a keyboard-oriented system is considered as a dogmatic.

It's not my case. I just think that when you deal a lot with text, like a developer, letting your hands on the keyboard is way nicer, instead of switching all the time between keyboard / mouse.

But I love to use the mouse when I'm on Gimp, or when I do some music, or when I post process some photos. You should use the best tool depending on the task.
