So I'm buying a new Macbook Pro soon, and it has to be a 15". Right now, I'm leaning towards the base 15" cMBP. I plan to replace the stock HDD for an SSD of my own (Samsung 840), I also plan to replace the stock RAM with RAM of my own (Samsung 2x4GB DDR3 1600). Before I pull the trigger, I was wondering if there's any reason I should be considering the rMBP over the cMBP? I mean, I only really envy the native HDMI port and the retina display, all that 'it's thinner' mantra doesn't mean much to me. Will I regret buying a classic over a retina?
