Nah, it's just a port. It's not a new protocol. So the only new things it brings over USB-A is Thunderbolt and extra power pins.
Guys, you are tech enthusiasts and I understand your hype, but let's be realistic: normal buyers don't give a penny if it's new or not. They will buy devices that work for them. And right now, only type-A devices work for them because they only have other type-A devices.
Now let's take a different example:
It's an analog port, and when LCD came, it just didn't make any sense anymore. LCD screens were much better, and for them to work, they had to receive digital data, not analog. That means VGA introduced another step of conversion. The computer generated digital data, it was converted to analog, transmitted through the cable, then converted back to digital again to be displayed. So it doesn't make any sense to use this terribly outdated tech. Oh wait... it's still there. Even though we don't have CRTs anymore, it's still included in new motherboards after 15 years of its obsolescence.
This is an extreme example, but it shows very well how slowly the market accepts new standards. At first nobody had computers with digital ports, so they started making LCD screens with VGA connections. Then people started getting HDMI or DVI in their new computers, but they still had their VGA-enabled LCDs so they continued using them.
Now, VGA had a very strong reason to be wiped from the market. It was analog. But somehow, it still remains. And USB doesn't have such a reason. I mean yeah, it doesn't support Thunderbolt 3 or have those extra power pins, but it's still a nice standard that can be used. It doesn't introduce any extra problems with current technology, it's not troublesome. In other words - it's not obsolete.
Furthermore, it's much more widely adopted than VGA was at the time. VGA was only used to connect computers to their monitors, and USB-A is used everywhere. Not only computers, but also TVs, set-top boxes, routers and basically anything that has an OS. USB-B is also used very widely, but it's for those devices that act as slaves.
So, tell me, what is your big reason to believe that this not obsolete and much more widely adopted standard can be replaced faster than VGA?
I stand by my word: until all my computers, TVs, set-top boxes, routers, and even the computers in libraries/schools/my friend's home get this new port, I'm not buying any peripherals with it, as I want to be able to use them everywhere I go.
USB-C will very quickly find its place in laptops, but only as a charging port or as Thunderbolt 3. Other devices will remain type-A. Just like micro USB replaced phones' charging ports quickly but never found its way into computers.
