Hey guys. I'm a high school senior who is looking to major in biochemistry in college. Right now, I have an aluminum Macbook from late 2009. I'm debating whether I should look to replace it for college or keep it. It's still running decent, but I'm not sure whether I should look into upgrading to a Macbook Pro or Air. I don't know how the new laptops run in comparison to the old aluminum MacBooks, so I wanted to see what you guys think. I'm really not into gaming, so that isn't an issue. Thanks for any help!
