I am looking at becoming a first time Mac user but I am unsure what to buy. I am looking at either the new 13" MBP or a good deal on a refurbished 15" laptop. What I don't know is how to make sure I am getting the best overall deal for my buck w/o going overboard for what I need. The 13" MBP I have been looking at is the 2.26 GHz model with an upgrade to its Ram/HD after purchase. An example of the 15" refurbished I have seen in the past was the 2.53 GHz model with the 9600/9400 video cards. Longevity -I am looking for my product to last at least +2 years. (Ie: Software released one to two years from now should run on current Mac within reason.) Portability -I am a full-time college student in a non-dorm setting. Looking for easier ability to take to and from school w/o being a complete nuisance in a classroom and/or library. Gaming I am not looking for a gaming laptop but I'm not dead either. If anything I am looking for something that could play Starcraft 2 and/or Diablo 3 depending on release dates. In the end I have no urge to spend more than what I need, but I am just not sure the limitations if any that Mac hardware/software designs may bring over an extended period of time.
