For instance, you can plug a 5K display to your iPad Pro and show some video on the external display. It’s still unclear how it’s going to work when it comes to software, but it opens up a lot possibilities.
You can also use USB-C dongles to plus all sort of data accessories. SD card readers, Ethernet cables, etc. The iPad Pro is looking more and more like a traditional laptop. Many third-party accessory makers will probably use this opportunity to develop docks and other hubs.
Finally, the good thing about USB-C is that you can theoretically turn any device into an external battery pack. Using a USB-C to Lightning, you can now charge an iPhone from your iPad. It’s an expensive battery pack, but it can be useful for those who always carry both at the same time.
Now let’s hope this is the first sign that USB-C is coming to the iPhone. I can’t wait to use my laptop charger to charge my phone, or my iPhone charger to charge my Nintendo Switch.
