Apple doesn't change connectors often. That is not the problem.
I don't know why you're complaining about the Apple connector, Dobbs. Apple has changed the connector only 2 times in the 13 years since the release of the iPod (from Firewire to 30-pin, and from 30-pin to Lightning), and they've used the Lightning connector for 2 years already. Likewise, Apple laptops have changed power connectors just 3 times in the past 16 years. I know you're slowing down in your old age, but I think this complaint is something you should keep to yourself.
In the same time, other companies have gone from proprietary mini-barrels to mini-USB to micro-USB to micro-USB 3, and now they're contemplating USB 3.1 type C. And you almost never can use the same power adapter for 2 different PC laptops, even from the same manufacturer.
What annoys me is that the Apple cord designs seem to be inspired by explosive seed pods. Bring your cable around and use it regularly, and before long the shell is splitting apart and the wires are unraveling. I get around that by exploiting the power-efficiency of Safari and the marvelous battery life, to leave my power cable safely at home. And Apple charges way too much for their cables; you should be buying Lightning cables on sale from an online retailer like NewEgg.
