Just like many of you, I am debating whether I should wait for the presumed update of the haswell rMBP, or go ahead and get the current model. I will definitely need one before I go to school in September, so I was wondering how your experience has been with the current rMBP. I would be getting the 13-inch model with an upgraded SSD and CPU. I herd there were issues with the retina screen "lagging" as the haswell processor is not sufficient enough for the screen. I would not be doing any gaming what so ever, but I herd this "lag" comes from normal scrolling? Just trying to get an idea here if it comes to September and I need to get the current model, are there any common issues people have. Thanks!
