Maybe I'm the exception here, but in a decade of using MacBooks, I've never experienced the power adapter falling apart.

I remember this a lot back in the PowerBook days, especially those clearish gray translucent adapters.

Apple has a fetish for putting weak boots on their cable ends, so if you tension them too much, the jacket of the cable will fail.

Personally, I've only had it happen to iPhone cables that get abused in the car. Still, it's a ridiculous problem to have when almost no other quality cord is so fragile.

I've only had one iPhone cable come apart on me and my power cable from my Thunderbolt Display shows some wear but I've never had a cord for any of my MBPs get loose or breakdown in any way. I've got at least two bricks/cords from 2008ish that I still use with an adapter.

I've had frayed insulation with multiple MacBook adapters and Lightning cables. I wonder if it is climate related; I live in a hotter and more humid place than Cupertino. In any case there is no excuse for the insulation being so fragile when $5 USB cables never have this problem.

Yes, me too, I'm sure the heat and humidity is a factor, but for the insulation to actually decompose in this way just from the climate is absolutely unacceptable.

I just replaced an Apple power brick from 2008, because the MagSafe plug wore out. The cable and attachment point at the brick were as good as new.

Same. I still have an adapter from a 2006 MacBook Pro which is used daily and not a hint of damage on it bar scuff marks.
