Importance of a Pencil?

I brought a couple of pens with me to college, and I haven't even touched them. (Only used them to sign documents.) For lecture classes, I usually whip out a pencil. I find that I can organize my notes better than a pen cause I can erase and make it look neat, etc. I used to smear, but after a while, I stopped smearing my notes (I'm a lefty.).

I guess it's the eraser and how the pencil marks on paper makes me want to use a pencil more than pen. Blue ink ftl.

EDIT: Oh yeah, I love the sound that the pencil produces when you write across clean, fresh paper. Now I sound like some pencil lover. :<
