I don’t know about the UK, but in the US USB-C is becoming the new standard. It is what my two computers have (Mac is only USB-C, my Dell has both) as well as the current versions of the iPad Pro.
Transfer is much faster than using WiFi either direct to computer or iPad. Also, USB-C lets you charge battery in camera, not sure if it would work with the lower wattage of the older USB chargers. If I go somewhere one less thing to bring, I already have my computer charger and a USB-C brick for the iPad so I can leave the Canon charger at home.
Hey, can I ask what Mac and Dell you are using? Microsoft don't seem to have USB-C on any of their products (which seem to be arguably some of the better specs on the market). Only the Surface Studio has USB-C and that's not a Thunderbolt port. I was looking at Macbooks though wasn't too keen on the spec /screen. Good point about using usb charging.
Taking the SD card out and into my pc SD port is working fine, and I'm actually starting to prefer it to using a cable
