if i hold the screen at a angle should it move down?
or should it hold still? on the 15in unibody.
Don't kid yourself that this is a design 'feature'. It is a fault in the manufacturing process.
I think it's ridiculous that the screens close on themselves as well, but it can't be a manufacturing process fault if there's literally thousands and thousands of these mbp's and they all do it. Go into any apple store anywhere in the world right now and all the floor models will do it. Bad design, absolutely. Defect, I doubt it.
The hinge is designed so that it's weak enough to be opened without moving the lower half of the laptop, while still strong enough to keep it's angle on 95% of computers during normal use.
I am so sick of hearing about how it's "designed" that way. As I mentioned above, if it was on purpose it was a stupid idea. I don't want to hear that my computer is "supposed to suck". I hate the hinge. I'll deal with it through the life of this machine but I'm not alone in hating this "feature" and I just hope Apple has heard everyone on this issue regardless of whether or not they did a crap job on purpose or lied about their neglecting to think that a notebook hinge maybe shouldn't wobble around.
