Dropped Macbook - hinge bent?

Well the unthinkable happened to me this morning - as I was getting up from using my Macbook the loose end of an ipod cable that was still connected got caught between my toes and my macbook went flying off my desk while it was still open. It landed open with the screen and keyboard facing down. Luckily it somehow didn't get damaged (as far as I can tell so far) except when I close it the lid is a little out of alignment. This thing is more rugged than it looks! My first question is, is this something I should bother getting fixed, as far as the magnetic latches not being lined up exactly?

Also, should I take it to a genius bar just to have them check it out and verify that it still works after being dropped in case something goes wrong in the future? My thinking is that if something like the HDD goes and they see the misaligned lid as evidence of a fall, they wouldn't want to fix it.

Thanks!
