Hi all, I am considering buying a 27" iMac quad core i7 refurbished 2009 model. It is pretty reasonably priced at $1369. I basically want it for the times where I feel my 13" MBP doesnt have enough screen real estate so I can just plug in my MBP and for running virtual machines for my computer development. I don't really care for the TB ports on the new models and don't need the graphics processing power. If I ever need to use anything for the Thunderbolt I would use the MBP. What do you guys think?
