Usb-c is very wide spread, but cos it's not on iPhones, it's considered sparse.
It's been on laptops for years, mobile phones at least 5 years (last year was on all the best android handsets). Even apple Mac's for a couple years.
So to call it new, is definitely wrong. To say not a lot have it, is wrong... It's only iPhones n iPads that have yet to add the "C".
People have been screaming for USBC stuff for at least 2 years. It's ONLY because apple said they'd put it in iPads, that a ⅓ of the market have woken up and said we need more, have some manufacturers woken up to putting more/or their first stuff out there.
