Maybe i'm just lucky, but i've never had an Apple cable break on me.
My original iPad 1 cable still works (and is still used occasionally).
Then again, i use my cables for charging, and i never use my devices while charging, so the bending/pulling that destroys most cables never occurs with mine.
One thing that does destroy cables though is a 2 year old kid with a fetish for sucking on the lightning end of the cables. My youngest kid did that for 6 months or so, and every cable he sucked on has a visibly corroded 3rd pin.
