I sold my old 15" MBP . I do marketing work. Work with RAW images and primarily use Lightroom, Photoshop, Illustrator and inDesign. I went with the cMBP body because it felt more comfortable with the concept of being able to upgrade when needed. HOWEVER. I keep feeling inclined towards trading it back to Best Buy during my 30 day return policy and getting the rMBP. The ONLY thing that is killing me are these issues: * rMBP issues with WIFI * rMBP issues with UI latency * rMBP issues with screen retention * rMBP issue with non-upgradability... I would like my MBP to last at LEAST 2-3 years.
