Re: What are you doing without usb-C?
Interestingly type-c does not mean usb 3.1. People are able to use the port, on early versions of usb.
But in general people just look for high numbers and don't think about the real world application. SSD for example - everyone talks about sequential read/write, but unless you are copying between two drive of equal speed (and when is that going to happen lol), that's pretty useless.
Same with usb 3.1. Its good for...hmm, video...and high speed hard drives. So if you have that external raid 0 dual msata drive (like your just super impatient about copying files damn it!), or egpu, or super hi def webcam - great (although you only get to use it, if the bandwidth is top notch, end to end). For video output a display port or hdmi does the job. And its common.
usb-c as a standard is good for phones because enables charging at the same as peripherals...but then that's only good for something like continuum, and that has limited applications.
Being two way doesn't help much for laptops, as you have to carry a charger round anyway.
It's useful in that its fast but small. Its easier to plug in. It's also useful if you have room for few ports, and you want one that can do everything.
But then if you have wireless charging....its only for peripherals, or connectivity....in which case everything you use over it, has to be fast enough: Does that phone you are using have an ultra high speed NVME SSD inside it? Is your external hard driver 10 gbps or more?
I think its good, but its more of an enabling technology. Its overrated right now. Most things use type a, and most applications are plenty happy on usb 3.
It has it's uses, but it's practical use is not as high as faster internal disk speeds, ram speed, cpu speed, bigger battery life, richer colour display or other features. In fact its practical use is pretty low right now, given micro-usb and usb 2 is still dominant, and usb 3, is still trying to catch on.
Even if you used usb-c heavily, the hub you were using for it, would come with type a ports, for mice, keyboards, usb sticks, hard drives, printers or whatever else.
Its a good thing, but definitely overrated. And it's not being adopted quickly. Phones use it now, but very few peripherals.
