Aside from being proprietary ($), is there any benefit of lightning over USB-C?
Step back in time- even a few days-
BEFORE Apple actually adopted USB-C in the iPhone and you could find
many passionate cases for Lightning over USB-C, with lots of rationale.
Now that Apple has actually done it, I suspect that passion is quickly evaporating and will be near silent within weeks. See collective sentiment about phablet-sized phones, NFC (pay by phone), etc
BEFORE Apple adopted them and then how so much seemingly extreme passion just vanishes afterwards.
I suppose to fault USB-C now means one is faulting Apple directly... while before USB-C was "terrible, wobbly, fragile, lint-magnet, etc" when it was only
rumored to go into iPhone, though virtually no one slinging such comments seemed willing to call Apple out for using it in the rest of the product lineup (for years now)... with no GOV mandate by the way.
There was lots of venting about Apple being forced to adopt USB-C but that was only an EU law. Just as Apple makes versions of iPhone with SIM cards for select markets, they could have made a USB-C one for the EU only and retained Lightning everywhere else.
Apple chose to go USB-C. And now most of the crowd would have to directly fault Apple for doing so. Since that seems to be forbidden in the Appleverse, USB-C is magically promoted to being a great choice now that Apple has made it. Already the broad chorus against USB-C seems quite a bit quieter.
Could we now fire up why no one needs 8K video in iDevices, nor an 8K AppleTV... until Apple adopts them? Or why no one at all needs Vpro before anyone can buy one... until they are for sale? Or why an iMac "bigger" has no place in the lineup until Apple resurrects it? The car is dumb until Apple rolls it out? Foldable phone is a gimmick until Apple unfolds one? Etc.
Just pick a feature some competitor has that Apple does not have yet: "99.9% don't need it", "it's stupid", "here's 6 things wrong with that", blah-blah-blah... UNTIL Apple adopts it and then it becomes "shut up and take my money" and "how did we ever get by without..."
I for one welcome Apple finishing what
THEY started. Each passing day approaches the finality of "one cable to rule them all." 🎉
