Hi All, So I'm a web designer, and I mainly do work on my 27" imac (fully upgraded late 2010 model). Was $2,200 I believe. However, I been having the urge to sell it for a 17" 2.5 model. I valued my mac via Apple trade-in, and it's worth less than 900. I definitely did not think the resale value for the iMac would drop that much. What's crazy is that I sold my Blackbook 07' for $600! Love the portability, and I think the screen size will manage, since it will already be large. What do you think? Apple refurb has the the 17" 2.4 for $1,800 but I just want the top-of-line for I guess a little bit more "future proofing" Thanks. Mac.
