Samsung's cables that ship with the SGS3 have Apple-esque crappy strain relief also.
I firmly believe all of this revolves around user-error more than the cables themselves. I never wear out cables, of any type. All my iDevice cables, earbuds, etc of all vintage are pretty much in pristine working order, as are all my microUSB cables. I'm not even particularly careful with them, I don't even really consciously think about using them.
My wife on the other hand can wear out any type of cable in record time. I've never really observed what exactly she does that's so hard on cables, but she has several iDevice cables that look exactly like the worst examples in this thread. (Weirdly, all of them still work even frayed like that). A pair of mini headphones will last her at most about a year- beyond that and it's a knotted tangled mess, frayed connector, with a short in at least one channel.
Annnnyway...
It's funny how I was hoping Apple would put more thought into the connector this time around. Seems like they did- in completely the opposite direction I was hoping for. (Making it harder to maintain third-party support rather than easier, and moving toward more-proprietary/costly for the user vs. less.)
