I found I had no need for a laptop over the course of my college career. Why? For one, I prefer taking notes by hand. Not many other students use a laptop in class, especially in liberal arts. For two, if I wanted one to tote around the library with me, my school checks out laptops at the circulation desk. I can save my work to my server space and access it from any computer on campus as well as my home computer (after some configuration). My school, being an engineering school, always has top of the line computers, so I just find it easier to use theirs
