People are questioning the inconvenience of carrying dongles based on their small weight and size. It's not about that—their weight and size aren't that significant. Here's why they're inconvenient:
With my 2014 MBP, when I went onto campus to give a lecture (pre-COVID), all I needed to take were my laptop and wireless presenter. That's it. No charger, nothing else. I then plug the projector's HDMI cable into my MBP's HDMI port, and my presenter's USB key into my USB-A port, and I'm ready to go. At the end, I unplug both, and I'm done.
If I had a current MBP, I would instead need to do the following:
Check my case to make sure I have all needed dongles. Once in the lecture hall, I get the presenter, the HDMI dongle, and the USB dongle. Plug in the HDMI dongle, then plug in the projector. Plug in the USB dongle, then plug in the presenter. At the end of the lecture: Unplug the USB dongle, then unplug the USB dongle from the presenter. Unplug the HDMI dongle, then unplug the HDMI dongle from the projector cable. Don't forget this last step! At the end of class I'm typically taking questions from students, and then need to clear out for the next lecturer; in my haste, when I've used a laptop that does require a dongle, I've sometimes forgotten it and left it plugged into the projector cable in the lecture hall. To those who ask: Why don't you unplug the projector from the dongle first, my answer is that it's more physically natural for me to remove it from the computer first.
And to those who want to argue that these are all quick steps and should be no big deal, consider that plugging in a few accessories for charging each night is also no big deal. Nevertheless, people really like the convenience of wireless charging so they don't have to bother with that.
