I own a 2012 cMBP 15", I had hoped to buy the retina version but since it was about $400 dollars more I didn't think it was worth it. I have since upgraded the 500gb hard drive to a 256gb ssd and had planned on upgrading the ram from 4 to 8gb in the near future. I use my laptop for a lot of web design work, graphic design, and 3d rendering. My main question is: will the cMBP's resale value depreciate quicker than usual because it is now a discontinued model? In other words, am I better of selling it now and buying a rMBP of waiting a year or two before purchasing one? Also, if you think I should sell it, can you give a price you think is fair? 15" late 2012, 2.3ghz i7, 4gb ram, 256gb samsung 840 pro ssd with stock 500gb hard drive included. Thanks!
