Replying to Can Anyone Spare Some University Advice?

Ok, so I'm about to move away to school soon, I still haven't bought a laptop. Lately I have been wondering if I even really need one. I have a brand new home built desktop that I use for gaming and can be used for writing papers etc.

I am living off of a limited salary and I would love to save some cash for skiing and ski gear, by cutting out spending around $800 for a pure class laptop I could definitely lessen the strain on my wallet.

I am taking a Business program at school, I have english, economics courses and a commerce course under my course load. Can anyone give me some advice? Will I be lost without a laptop in class?
