Parents to a MacBook Pro persuade?

I'm 15 years old (March 16) and would like to have a MacBook Pro. Before everyone says that I do not need it in my old age, etc. I would be glad if you would listen to me before.
It's not that I do not need it because my school does everything on laptops and so I'm forced to own one. At the moment I use one of my father which he also wants to borrow all the time and so on. I have had good grades and never had problems at school. I would like to pay for the laptop myself, however, I have never received a cent pocket money nor I spend anything (Christmas gifts or birthday gifts I do not get). Because of the move, I'm sitting in my room all day doing homework and rarely leaving the house, and my life is just passing me by. I did not want to move but my parents. I have never had any problems with my parents or anything else. Well, that we could not afford that is not true because my father has recently bought real estate.
It does not have to be the newest but I would like to have one for free time and school…

So now that you know my situation better, I would be glad if you could give me tips and arguments for it. Please do not write that I do not need it, because I do not… But I want one.

Argue that you have delivered good and otherwise have apparently nothing on solemn occasions (Christmas, birthday) have received or not even pocket money - which is really hard, because you will need, believe me.

Oh you want to cut videos or what else do you want the mac with its extremely cool apps but ##### kace so bad price ratio of the hardware
