Hi, is problem in this video normal? It is Macbook Pro 15" mid 2012 with 1440x900 display. I have information from repair shop, that it is OK and it is feature because of display weight. If this is OK, is same problem on antiglare 1680x1050 version? As I read, HiRes antiglare (that I can buy too) display is 50g lighter. If someone have Macbook without this problem, can you make video and upload it to youtube? Thanks.
