My Current MBP is mid-2009 2.53Ghz C2D w/8Gb RAM I am watching the Prices for 12Gb and 16Gb ram kits, 500GB - 1TB HDD, and 512GB SSD's dropping relatively radically. I am also considering replacing my current MBP to a refurbished 2011 13" MBP model and upgrade the RAM and HDD to higher capacity HDD or ~512Gb SSD, in tandem. I am going to be running Adobe Creative Suite Design Premium, Maya & Mudbox, and Painter 12. Not all of these applications will be running at the same time, but I expect for workflows I may have say maya and photoshop extended running at the same time. RAM, Stability, processor speed, and small size are my key points. For as long as I can, I will stick with the 13" MBP's and use an external screen for additional workspace.
