I think this is a common desire for many users now, we want to just plug in one thing and go. This is why the USB C docks discussions have been so popular, because the potential convenience is huge.
But then the question becomes, why is it so important that the V be “King of Ports” if what we really want is to only have to use one cable? BTW, I think this is the methodology Apple and Microsoft are using to design there hardware right.
I think the reason is because that the tech world is simply not their yet. We want to live in a one cord wonder world but we know we can’t yet. We have to many things that need those USB A ports, our monitors don’t have USB C ports, people can’t agree on whether or not USB-PD is a good thing or not, and most people still need a good old fashioned headphone jack because they (logically) don’t want to buy new headphones or use a dongle.
