Nope. I pass data around over the network, either via cloud or P2P. If I plug into an external display I use BT kbd/trackpad. And I do have a waterproof/shockproof camera with an SD card but I don’t use it every day, or even every week; I use my phone.

Flash drive? Hardly ever used one; networking existed before they were invented.

Yes, but so rarely does that use case actually happen. It has been fine with a dongle and not ever been a space issue. I carry a USB-C to A dongle with me at all times wherever my laptop goes. It basically lives with the laptop. Works just fine for every use case I have and it’s often the thing taking up my second slot. A bit annoying, but a fact of life. All SD card stuff happens on my desktop - anytime I need an SD card to connect to a computer I’m always at home - I’ve never once had that requirement on the go. External keyboards just don’t get used at all - I paid a bunch of money for a nice keyboard built into my portable machine, in fact one of the reasons I purchased the 2020 MacBook Air was because they got rid of the butterfly keyboard - so I don’t really use external peripherals with it.

Or just an external keyboard...

I'm using a BT mouse explicitly not to bother with a stupid "2.4GHz USB Receiver" and keep one (USB-A!) port free.
