What I have: Early 2011 15" MBP with 1680x1050 high gloss display, 2.3Ghz i7 processor, 16GB RAM, 512GB SSD and 480GB SSD in the optical bay. It was quite a high spec when I bought it in November 2013 then I upgraded the memory and additional SSD. Purchased used on Ebay for $900 and spent an additional $500 on the upgrades. I have an opportunity to buy a 2013 15" rMBP with 2.0Ghz i7 processor, 8GB RAM and 256GB SSD for $900. I could upgrade the SSD and selling the old MBP would offset some of the total cost. Motivation for considering this. Desire for the Retina display, fear of Radeongate and its a low cost transition. 16GB of RAM is nice but do I really need it? Probably not I am not a power user. Would you do it?
