Had a 2011 Macbook Pro. Was always very nice to the charger, never abusing or dropping it. But Apple's decision with all their cabling to not incorporate strain relief was frustrating. I went through four chargers in four years. Why does Apple continue to ignore strain relief on their cabling?

You're not really doing Jobs any favors. Instead of saying Jobs was a liar, you're saying he was an ignorant liar.
I disagree - a lie is told knowingly. If you say something untrue without knowing it is untrue, it isn't a lie.
It might not be a lie, but it is bullshit.
> On Bullshit (2005), by Harry G. Frankfurt, is a philosophical essay that presents a theory of bullshit that defines the concept and analyzes the applications of bullshit in the contexts of communication. As such, bullshit can be neither true nor false; hence, the bullshitter is someone whose principal aim — when uttering or publishing bullshit — is to impress the listener and the reader with words that communicate an impression that something is being or has been done, words that are neither true nor false, and so obscure the facts of the matter being discussed.[1] In contrast, the liar must know the truth of the matter under discussion, in order to better conceal it from the listener or the reader being deceived with a lie; while the bullshitter’s sole concern is personal advancement and advantage to their own agenda.

#23I really hate how weak they made the strain relief. I found mine frayed within a year of use (in and out of bags and often hastily "wrapped up" in exactly the way the device suggests one should by form... but which everyone advises against). So I did what any enterprising hacker would and tore it open to strip and re-solder the connection... only I found super-thick solder points and don't have a strong enough gun to…

#25Fascinating. The magsafe connector is awesome in preventing something snagging the cable from dragging your laptop along with it. But, as the article says, reliability is a problem. The thing is definitely not toddler-proof. I have a 2012 Macbook Air, and I'm on, I think, my fourth charger.

The 43% profit margin mentioned in the article definitely won't incentivize them to improve.

I've bought two replica chargers for $20-30 off ebay.. i'm on my second. The first one lasted a year, which is about how long my original charger lasted due to the cord fraying
The OP shows why replica chargers are not a good idea. You're lucky if it doesn't destroy your machine.
While a couple of them have died, so have my original three MacBook chargers. None of them has killed or damaged mine, or anyone else's MacBooks.

#28The LED in the Macbook power connector is programmable? Has someone written a tool to make it blink or something?
The same guy did a write up on the protocol used to communicate with the magsafe tips. It can also be used to trigger the above LEDs: http://www.righto.com/2013/06/teardown-and-exploration-of-ma...

#30Otherwise, Apple makes ridiculously durable products that I use for years on end. It's just weird that their charger's wire almost seems purposefully designed to break in this manner.
This isn't just a minor annoyance and monetary concern where I'm just annoyed at having to buy a new charger every year or so - there's a real safety issue here with this wire being so fragile - it could be both a shock and fire hazard.
Shame on Apple for ignoring this very real problem with their product.
