There's a pretty large market of people who want to use a desktop, with its large, dual monitors, high-capacity external storage, printer, high-speed wired network, physical mouse/input device when they're in their office, but still have the flexibility to carry a relatively high performance computer with all their stuff to meetings.
Simple usb dongle/expanders are much easier - I've got a 4 port with all As, a usb-mSD adapter, and a A/C adapter, and I don't think I paid $30 for the whole deal. Something like https://www.amazon.com/dp/B09MLRPTT2
That 3-port variant is close to what I'd like, I couldn't find one like it. I still wish for a bullt-in mSD reader, as that's another device to carry, and a short cable instead of a direct USB port...
But yea close enough I guess, I'll see if I can find one like it. Thanks.
