I currently have a 2006 Macbook I got while I was in college. She has served me well, but it is time to upgrade. I am trying to figure out what to get and I am hoping based on the info provided you all can help me make a decision I use my laptop everyday for professional and personal use. I am a freelance designer (dont ask how I have gotten by so long with the 2006 MB) and use CS5 pretty extensively. I dont really do much gaming on my laptop, but will probably do more once Diablo 3 comes out. I have a display and keyboard/mouse set up so screen size is not all the important to me. I have like the 13" for its portability. Obviously pretty much anything I buy will be a huge upgrade over what I have currently. Here are my questions: Is the price increase worth the performance increase in the 13" models? Is the base 15" worth the price increase over the 13" model? Would it be best to wait at this point for the next spec refresh on the 13 models or will that be a long wait? Which model would best fit my needs? I am trying to decide between the 13 models and the base 15 model. Those are what my budget will allow. Finally, is there anywhere to sell or trade in old Macbooks and iMacs (other than eBay)? Thanks for all your help guys!
