We love to talk about the quality of out Apple products... whether it be out laptop or iPhone. My beef is their memory slot setup on their MBP. Sure wish it was was not staggered so that the memory would not lie ontop of each other. As well, use metal *retention clips* versus plastic. One of our newer 8Gb modules, when laid 2X won't allow the memory to sit right due to staggered setup and just a HAIR enough that the memory will sit in the rentension clip, but will just *pop* back right out with the slightest of movement.
