> Was traveling in UK, and laptop keyboard cracked - big hole in the side of the keyboard. Took it to Apple store in London - forget which one - replaced at no cost in about 3 hours.

Same thing happened to me (white Macbook, cracks on the keyboard). AFAIK it is a known defect from this series and Apple accredited repair shops were instructed to replace the keyboard for free no matter if the warranty was still valid or not.

It's still a good thing though, I know no other brand that would do that for free 4 years after the warranty expired (in my case).
