Hey everyone! After looking around online on Black Friday, I came across a brand new rMBP that was sealed and had top specs (2.7/16/768) for $3350 total. I bought it to either keep or resell and now I'm not sure which to do. My question to you guys is how much of a difference do you think I'm looking at paying to keep the rMBP if I sold my 17"? It is an early 2011 model with a 2.2GHz i7 processor, 16GB RAM, 512GB SSD, AppleCare until 4/2014, and I'd include an optical bay kit (with the original 750GB HD), all original accessories, the 4GB RAM it came with, and a USB 3.0 card for the expansion slot. Another issue I have, though, is that if I open the rMBP, I can't really sell it as "new" right? I was wanting to check and see which screen it had as part of deciding what to do. Your help is appreciated.
