So I was thinking of picking up a mid 2012 MP Retina up from BNH online the one with 512 SSD and I was just wondering did they end up fixing the retina display ghosting issue? Please advise! 512 SSD is really important for me space wise and the cost of the current macbook with all the upgrades is proving quite costly. Please advise if I should pull the trigger on the old model. Thanks!
