The only actual features of the lightning connector are that it can be used by people who have suffered too much brain damage to understand spatial orientation
One way sockets that are hard to get the right way around first time annoy people. If you haven't noticed that, then you are very unobservant. If you think that kind of annoyance isn't worth fixing with new sockets, then you are an idiot.
Good plug & socket designs go in the first time, and don't require looking. Take the jack plug as an old, yet excellent example.
To be fair, a cable that is plugged in daily is a very different use case than one that is plugged in once and left plugged in until a component is replaced. The design tradeoffs are different if it gets a lot of plugging in/out action.
Yeah, I totally hate HDMI cables too, they suck! So what if I can get pure digital HD video and audio on the same tiny cable, as opposed to the five required for component (with stereo sound and lesser vidoe quality). I just hate having to actually look at the cable and port I'm trying to plug it into: I'd much rather just jab them together blindly until it goes in!
Same goes for DVI, S-Video and even VGA! Yeah, screw them all, I'll stick to composite, man! Fight the power!
