slanted vertically? Even the my first gen Macbook had such imperfections, but it doesn't affect the function of the, well, function keys. I think it's just because of the way the keys are separated and attached to the body by so many screws (more than 50 tiny screws from what I've read somewhere). Since the new unibody MBP has used the MB keyboard design, I think your observation is quite normal. Or your keyboard is much worse?
it's like this http://forums.macrumors.com/showthread.php?p=6584504 my esc and f1 keys are slanted to the left and my left command key is slanted to the lower left of its corner like 30 degrees. My option key is slanted to the right. it's very noticeable when the keyboard light is on. Anyway, i already brought it to the service center and they categorized it as defective. they're replacing the whole keyboard.
Where did you take your MBP? I have the same issue with my MacBook, I'd like to have the keyboard replaced too.
