HELP ME DX

So, yesterday this guy (i think his name was Trevor) came in and told us about the brain. It was really cool and neat :3 and the awesomest part, HE HAD THE COOLEST LAPTOP EVER!! Well, probably not cool to you, but it was too me XP Since the two computers that I have in my house are an old laptop that barly works, and the stupid windows computer that i'm using to write to you right now,  I really liked his Macbook. It was so AWESOME!! And you probably don't know this, but i'm trying to get a new computer, so I can make better vids for you  guys :3 The only problem is... I gotta save up all the money >:

So, I saw two computers I liked, the Macbook Pro and the Macbook Air. I was wondering which one is better, because they look excactly alike DX. I was also wondering what the prices were for them, cuz i'll probably go with the cheaper one if they have the same benefits :3 I'm guessing the Air one will be cheaper, but the Pro thingie looks cooler X3

Thanks!
