I never did get to know LaTeX very well. It's pretty much a mystery to me. However, I think if I ever took the time to sit down and learn it, I'd feel the same way as you. I like a nice pretty graphical environment to work in, but when it comes to getting work done I love the old Unix tools. I'll use Vim and Vim only to code, regardless of how good Eclipse is (and it is a fantastic product). I can't stand a cumbersome GUI that gets in my way.
Maybe I'll sit down and crap out a report or two in LaTeX this upcoming school term. Finally bite the bullet.
