The Keyboard is "Made" to have leaks around the key. Look more gorgeous and is more useful then having the letter lit alone.
I also did'nt returned my macbook. It does have slanted keys. At first it did'nt bothered me much. But at each time I look at it, it look worse and worse to me. I just can't return it anyway, since the nearest apple store is 2h of driving away and I don't have a car.
just do the fix that someone on here mentioned. stick something in on the left side of the key, pull it up and leave it that way for 30 seconds, then let go. i just did it and it totally worked.
