I'm going to college next year to major in computer science/engineering. I'll be programming a lot and working with different languages such as C, C++, etc. I want to get a Macbook because my college uses iMacs in some of their classrooms and one of the professors I talked to said I should get one. My only question is if I should pay extra for the 2.4ghz macbook or should I just stick with the 2.0ghz model. Is the extra money really worth it if I'm going into the computer science field? Note: I really don't care about the light up keyboard. It's nice, but I'm not going to spend extra money for it.
