Hi all, I encounter an offer of buying used early 2011 MacBook pro 15" Here is the spec 2.3 Ghz i7 Hi-res Matte screen 1680x1080 Top spec with 512 SSD Good condition Which price do you think is a good deal? US$1000? Or shall I go with a used 2012/2013 Retina 15" model instead? ( comes with USB 3) I need one for photo and video editing and wonder which way is better. Many thanks in advance for any opinions!
