I am planning to purchase a macbook pro sometime in the near future for university and am unsure what model I should purchase. Note: It is very unlikely that I will make this purchase before the pro lineup is updated. The main reason I need a good laptop is to run AutoCAD 2011/2012 and AutoCAD 3D software. I currently have this running on an older model iMac, 2.4GHz core 2 duo but it feels sluggish and sometimes freezes. I would like to use this as my main computer for the next 4 or so years, so the 13" mbp with 320GB hard drive and 4GB of ram would be my first choice. I don't care much for screen size because I have a good 19" monitor at home. However I am looking for the best deal in terms of price, processor speed and portability. Can anyone help me out with this decision? And does anyone have any rough estimates for the mbp updates? Thanks!
