I was wondering if you could open up your MacBook from a closed position, to the position you would open it to. Can you tell me if you get a slight wobble when you let go, or just the general stiffness/looseness of your hinge. The MacBook needs to be on a hard rigid surface or else it won't work. The reason. I feel my MacBook's hinge is quite loose. I just feel when I open it up, it should perhaps be tighter and more rigid. I seem to get quite a bit of wobble. I took a look at my friend's (newer) MB and it seemed a lot firmer. Somebody once picked my MB up by the monitor for a few seconds and I'm wondering if this has affected it. Thanks.
