I've read some pretty horrifying stories about Apple (this person had a cracked screen, Apple bricked the phone while attempting to repair it, replaced it behind his back, then charged him 3x -- they also have a required replacement device "security deposit" you must pay up front in order to even get them to attempt a repair):

There's a reason why third-party repair shops like Rossmann Group exist and make a killing doing component and board level repairs on iDevices.

I think that Amazon is best with their Kindle support. You break a Kindle and they send you a new one for free (if it is under the 1 year warranty) even internationally.
