I'm honestly really happy with USB-C. My phone, laptop and tablet charge the same way. I bring one charger and two cables, so I can pack much lighter than before. Each device can serve as a power bank for the others. My monitor serves as a powered hub, so there's only one cable connecting everything to my laptop. I use the same charger for everything from my camping lantern to my computer. I don't have a big box of cables anymore, nor do I pack 5 different cables when I'm on the move. It's very convenient.

It only becomes a problem when I leave my bubble. I usually travel without my adapters, so I can't borrow someone's mouse, or plug something into their TV.

Then there's the issue with cables and chargers. I have thick cables and 100W chargers, so it's never a bother, but it's not a trivial thing for the average user to make sense of.
