Hey folks! Actually I am running a rMBP 15" (early 2013) - base model (i7,256 SDD, 8GB). I am carrying it every day to work for my PhD doing researches, text-work. At home I am using it for some Diablo3 and mainly for image processing (working also as a photographer). So basically I am very pleased with my MBP. Why am I still asking? One of my friends is selling his iMac 27" (late 2012) with maxed out specs (3,4 GHz i7, 3 TB Fusion, 680MX 2GB, 16GB RAM. He bought it in April'13 with a 3year warranty. Now he is selling it for 1500 because he is switching back to windows. This mac is like brand new (I did some support during the whole period so the mac is 100% fine). It is a "special offer" just for me. Considering this offer I feel like I have to buy it. It would give me some great workspace at home for my photography etc ... In addition to the iMac I would buy an older Macbook Air 11" to carry it with me . Whats your opinion on that? Would you switch considering that offer?
