Lately, I have been contemplating ponying up for Retina 15" refurb -- I really have been drooling over the screen and my non-Retina display is chopped liver next to it. I think, if you've been in the market for a 15" Retina refurb, it is high time to get one, given the previous two generations are better than the current generation in some respects, regarding the base models of course. My question to you guys is, what do you think I could command for my 13" early-2011 MBP? Here are the specs: 2.3ghz i5 Sandy Bridge 8GB RAM 128GB Samsung 840 Pro 128GB Samsung 470 (in optical bay) Optical Drive (external in enclosure) The computer performs flawlessly but there are some cosmetic flaws. A few of the keys are like ghosted out to where you can't see the letter. Some blemishes and smudges here and there across the body. I probably won't proceed with selling it. I still love my machine. But, I'm curious what the difference will be with its resale value and the cost of a 15" refurb. Thx.
