We may live in the future, but many of us still work with people who live in the past. I know Apple always tries hard to be forward-thinking, but USB-A is one of those ubiquitous standards that won't disappear for quite some time.
I’ve been migrating to usb-c since my MacBook four years ago. I don’t have any A devices and just keep adapter dongles for people who have thumb drives or something.
I don’t care that much because it’s the size of a quarter and goes in my bad with hdmi and other adapters.
