I need to buy my son a new MBP for college-he is an architecture major. We are doing the education pricing. We waited for the new line to come out. I would like to buy a 15 inch but by the time I add 750 hard drive and at least 8 gb of ram the price is getting out of reach ( plus AppleCare and 1 to 1)! Not even considering the new Retina screen model-too much. I've compared the two new 13 inch MBP and configuring both machines to the above specs and the difference is about $100 more for the i7. Is it worth the additional money? Are there any 15 inch previous models left in stores for decent discounts? Can't find any in the Apple online store. Any suggestions are welcome.
