hey, im just wondering whether i should get the high end black macbook or the low end macbook pro? ill be getting into a university to pursue a degree in mechanical engineering soon, do you think the black macbook will be sufficient for running applications related 2 that field? (CAD,CAM, etc) portability would be an issue to me since ill be carrying the laptop around for classes, so is there much noticable difference in weight and dimensions between both laptops? entertainment is also quite a concern, is the macbook sufficient for running most new games such as call of duty 4 at low resolution? and does the 256mb and 512mb graphics card make much of a difference for macbook pro? and lastly, how about the aesthetics? how many of u prefer the blackbook over the macbook pro and vice versa? sorry for the long post, but i hope to get answers for most of my questions, and i hope to hear feedback from present owners of either macs, and tell me, will both last me for at least 3 years..?
