Screen misalignment

I doubt if it's a problem but if your concerned call Apple or take it by a store.

If you have an apple store nearby, take it in so you can show them yours next to a 'normal' macbook. On the phone they may tell you its normal but if they see it next to one in the shop they wont have that excuse.

While you have the warranty its worth making use of it.

My screen is also misaligned. I don't recall if it was that way when I got it last summer but I noticed it when I shut my Macbook the other day after using it. It sticks out a millimeter or so on the left, and is not flush on the right (it is off by about the amount of overhang on the left). The hinge seems loose because the lid will move into the correct position when pressure is applied from the left.

I don't know what to do about this either, and it bugs me that it is not aligned properly.

Perhaps take it to the Apple Store? I've heard of loose hinges, hinges tightened to much (causing the warp you mentioned), and the case cracking because of things like this. My MacBook is my baby, and the thought of damage to it makes me sick. >_<
