Those are part of the first things you learn in your first hour in front of a computer. I think that my comment is clear on my position on that "mouse debate": the mouse is an effective interaction device in more than many contexts but there's at least one context where using the mouse is not the most effective thing to do. Again, the problem is not the mouse itself but the cost of constently switching between it and the keyboard.
