Wow, so many people saying that theirs is the same! Mine, thankfully, is perfect. Nothing but straight lines on the front, same goes for the only other chap I know at work with an MBP.
It's definitely NOT normal, and as others have said, will be under the terms of the warrantee. In the past I've returned a PB because the keyboard looked to have a slight bubble effect in the top right corner - barely noticeable but it was there. Pretty much like your warp. Took it back, the guys at the Genius Bar were great - it was a simple case of them confirming the defect and going out back to get me a new PB!
Get yourself to the Apple Store - they're very understanding with things like this in my experience.
