Hi, I will be attending college this year and need a laptop. I will be bringing my gaming PC to college so my laptop will mainly just be for school work. I'm looking for something fairly light/small so it's easy to take to and from class. Also I need it to have a decent CPU because I will be going for a computer science major, and that has some intensive programs. My budget is around $500; I am open to new and refurbished products.
