Got my rMBP on Monday and it was great! Crazy fast and such. I was doing all the testings that everyone's been having concerns about such as the scrolling and such but I finally started testing for the ghosting and sadly despite the fact that my machine was (according to the serial) built on the week-ish of June 25th I had the ghosting/retention issue. I didn't wanna believe it but I ended up going to my Apple store today. I was the first of the kind within my area to have this issue and the ones who helped me had no idea wth to do. He obviously saw the issue and told me that this "should not be happening". Since they did not have my load out in stock (maxed out rMBP) they gladly refunded my purchase. However, I am now on the fence as to what I should do. Should I just reorder again right now... or should I wait for my local store to get them in stock. I'm just kind of paranoid about getting it again and was wondering for those who have had theirs replaced to share if their new replacement had no longer exhibited the ghosting/retention issue.
