Im planning on purchasing a 15 inch MacBook Pro, my wife is a teacher so Ill be purchasing it through the edu site. I was planning on getting the middle 2.66GHz model and upgrading to the 320GB 7200 rpm hard drive. But I see that I can get the 2.8GHz model with the 512 Vram and the same 320GB 7200 rpm hard drive for $160 more. I know for my needs I really dont need the 2.8GHz, the 2.66GHz model will be fine for me. I was just wondering if it makes sense to spend the extra $160 for the possible extra resale value when I sell it, probably 3 years down the road. Does thinking in those terms make any sense?
