Hello, I am currently a Graphic Design student at San Diego State. I need help deciding which MacBook Pro model I should purchase. Since I am a college student with a tight budget, I am debating whether I should get the 15-inch: 2.16Ghz or 15-inch: 2.33GHz model. So far, I am leaning towards the 15-inch:2.16Ghz because it fits my budget enough to purchase before the upcoming semester. However, it includes a slight low-end CPU and Video Card compare to the rest of the models and 1GB memory. Does the .17 GHz difference of the processor between the two models make a significant difference? I am planning to upgrade the 1GB memory into 2GB memory later on because I heard it's much affordable to purchase separately. Is that true? Please let me know, I am very interested in purchasing an Apple laptop. By the way, I am also able to use the education discount.
