Hi I have a MacBook Pro Retina 13 inch Mid 2014. I Really need a larger screen for daily use. I'm thinking of buying the new Imac 27 Retina, to get me a better screen. But again, my MacBook Pro have almost the same specs as the new Imac (almost ) Thats why I also think about the old Cinema 27 display from Apple. My question is. For a ordinary user like me, I dont work with 3 d or picture editing or anything. Is there such a quality difference between the 2 screens? I even think the old Imac have a beautiful looking screen Do I really need Retina?
