I ask this a lot of times that I see someone complain about the quality of Apple cables: what the hell are you doing to your cables? I've still got 30 pin cables with cracked plastic on the 30 pin end, but they still work. After over 10 years of buying Apple devices that have cables, I count one cable that has gone bad.
More of a rhetorical question I guess, as we're just trading anecdotes. But I find it interesting that some complain about the quality of Apple cables, whereas I have piles of them that just refuse to die.
