Hi. I am getting a laptop for high school next year. It is mandatory to have a laptop in my school. I am thinking about getting a MacBook Air or Pro. I would be using the laptop for school. I would be making movies from iMovie, using aperture and writing documents with Microsoft office. I was wondering which laptop is good for me; MacBook Air, retina MacBook Pro or Non-Retina MacBook Pro. This is going to be my first Mac.
