Is there actually any evidence to suggest Apple's 34-pin dock cables fail more often than others? I've owned 34-pin dock devices going back about 8 years now and I cannot recall ever having a broken dock cable. I have no doubt it does happen from time to time but from my own personal experience it doesn't seem any more or less common than other types of cables. I know plenty of people who lose them or want a second one to charge at work or carry in their backpack but where's the tar and feather brigade at Apple Stores over this? Why aren't my friends and family coming to me with mysterious charge/sync problems? At $30/pop if these cables were failing at a very high rate I would expect quite a lot more public outrage. It may be that since iPods and iPhones are replaced fairly often, and include a new cable, people have a cache of spares? If so doesn't that alone kind of shoot down the designed-to-fail argument? Why include a new cable? Wouldn't the increased support costs from telephone/in-store support for these problems be far larger than selling $30 cables? It seems like the typical Internet conspiracy that doesn't really make any sense when you start to look at the details and notice there's absolutely no evidence to support the original claim being offered.
