<p>I am thinking about getting a macbook for college, but I am having a hard time deciding between the 15" and 13". I am undecided about my major, but I will be taking some computer science classes. </p>
<p>I need to be able to carry it in my backpack without it being too heavy (I'm a small girl and weigh ~110 pounds). I also want something that will last for more than my four years of college. I will primarily use it for word documents, youtube, browsing the web, and watching movies/tv shows.</p>
<p>Which would be better for me?</p>
<p>Thanks!</p>
