They kept the 30-pin connector around far, far longer than most companies kept their proprietary power or data connectors. When they switched it was to something robust enough they wouldn't need to fiddle with it for a long time.

Standards change, but at least this one hasn't changed very often. I think "once" is an allowable amount of change.

If you bought a Galaxy S5, 3 chargers, 2 car chargers and a Bose devise for it and then upgraded to a S6, how do you think you'd fare?

I don't know. (HTC One) Did they follow Apple's lead and change their approach too?

Your inner fanboy is leaking. It wasn't Apple's lead.

Samsung did it at least twice before Apple switched to Lightning, another time after Lightning and will probably also move to Type C soon. Same for HTC, they switched port choices before Apple did as well, the HTC Dream has a different USB port than the HTC Evo and both came before the iPhone 5, and they're also likely to change to switch to this as well.

So basically Apple is the only choice that comes closest to behaving as you expressed a desire for and instead you shit on them out of complete ignorance. Good job.

You really are an evil duck.
