Ok so i'm thinking about buying a macbook air but this will be my first laptop and i know nothing about laptops. I'm about to start college and that's what i'll pretty much use it for. THis may sound retarted but is this laptop considered fast? You know when your surfing the web i cant stand slow speeds. o BTW i look up on apples page and saw that macbooks come with a music program that lets them edit, make music. Will this laptop have that program?
