bottom line, being in an aluminum enclosure the display part of mbp is rather heavy, therefore, you are unable to work if your workflow is that you put your laptop against the wall and look towards the ceiling (probably sitting on the wall, having your back on the floor.) i dont have such workflow so the hinge itself has caused me approx 0 problems till now.
I've read this "workflow" description a few times since the new laptops were released. I think I need someone to draw me a picture, because if it is what I think it is.... then I cannot understand why people expect this to work.
