Just to update you all on what I did.
First of all, I have discovered where the screen is screwed to the base and I'm not going to attempt a repair.
I am choosing not to take a refund and to keep my current MacBook Pro. It's not nearly as bad as some I've seen and it has made me re think and have a different view on it.
I will leave it be, and if there are any problems regarding this poor alignment (such as hindge problems, display problems etc etc), I will contact apple immediately.
But for now. I will keep it. As I said, if any problems crop up, Apple will be receiving a phone call from me immediately and we'll go from there.
Thanks to everyone for the contribution and replies. A true help.
