Interesting point. Got me thinking about how the iPod was not the first MP3 player, and how the iPhone was not the first smartphone. I believe the philosophy was "don't be the first; be the first to get it right."
It's a little disappointing that they haven't been so magical lately.
More likely than using any sort of standard port would be Apple inventing yet another new proprietary port.
False. USB 1.
Apple rarely goes proprietary with their ports. The original 30-pin iPod port. Lightning. ADB in the mists of time.
All of which were I believe better than what was available.
They are better, but we also have a situation where the only port on an Apple device is proprietary with the latest iPhone.
Of course, the one huge flaw is that now their phones and laptops use different connectors.
If we put the iPhone 6S model aside (because the -S models generally do not adopt a significant change in features), the only model released since USB-C is the iPhone 7.
Given the short lifecycle of phones, adopting lightning rather than postponing until USB-C has given several generations of phones with a superior connection.
Should the iPhone 7 have adopted USB-C instead of lightning? Perhaps, but USB-C support isn't exactly widespread (and it might in fact be Apple which ends up pushing USB-C support to the point of widespread adoption).
Is the lightning connection superior to USB-C?
Well, it's size is smaller: 6.7mm x 1.5mm (vs 8.4mm x 2.6mm for USB-C); a 42% reduction in height, and a 20% reduction in width.
For devices like mobile phones, I can see how the size of connector can be more important than bandwidth or compatibility. I'd like lightning to be a standard, but it's definitely an improvement over micro-USB, and in terms of size, it's better than USB-C.
