I seen a 26 or 27 minute review video on YouTube by I *think* MobileTechReviews where she was reviewing the 15" RMBP with the pink saggy flowers wallpaper on and and when she went to show another screen or windows I actually could see the retention of the Wallpaper a little bit on other windows. Like you could see an almost faint outline of it. Could you people with this retention problems tell me if this is something that goes away after a few minutes / half hour or if it once you get it it stays stuck this way causing for the need of a whole new replacement notebook or screen replacement, or whatever.
