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.
Go get the RMBP! It is amazing.
issues with wifi : 0
issues with UI latency: sometimes it lags when it's on the integrated, but at least you're saving a lot of battery power. when it's on Discrete it's flawless.
issues with screen retention: well, it happens every now and then on some displays, not a big deal, but if you can't live with it, replace it and hopefully the next one wont have this issue.
issue with non-upgradability: i think the rmbp will last you more than 3 years without upgrading. 16 gigs of ram is plenty, and the nVidia 650M is more than superb for a super light laptop. The SSD is upgradeable, and the processor is really good.
The screen and the weight of this thing alone make me love it. I take it to college every day and it feels so light and nice. The resolutions of every other screen sucks now, and I just love enjoying the best screen on the planet
